  • Solving Cubic Polynomials
    Solving Cubic Polynomials 1.1 The general solution to the quadratic equation There are four steps to finding the zeroes of a quadratic polynomial. 1. First divide by the leading term, making the polynomial monic. a 2. Then, given x2 + a x + a , substitute x = y − 1 to obtain an equation without the linear term. 1 0 2 (This is the \depressed" equation.) 3. Solve then for y as a square root. (Remember to use both signs of the square root.) a 4. Once this is done, recover x using the fact that x = y − 1 . 2 For example, let's solve 2x2 + 7x − 15 = 0: First, we divide both sides by 2 to create an equation with leading term equal to one: 7 15 x2 + x − = 0: 2 2 a 7 Then replace x by x = y − 1 = y − to obtain: 2 4 169 y2 = 16 Solve for y: 13 13 y = or − 4 4 Then, solving back for x, we have 3 x = or − 5: 2 This method is equivalent to \completing the square" and is the steps taken in developing the much- memorized quadratic formula. For example, if the original equation is our \high school quadratic" ax2 + bx + c = 0 then the first step creates the equation b c x2 + x + = 0: a a b We then write x = y − and obtain, after simplifying, 2a b2 − 4ac y2 − = 0 4a2 so that p b2 − 4ac y = ± 2a and so p b b2 − 4ac x = − ± : 2a 2a 1 The solutions to this quadratic depend heavily on the value of b2 − 4ac.

  • (Trying To) Solve Higher Order Polynomial Equations. Featuring a Recall of Polynomial Long Division
    (Trying to) solve Higher order polynomial equations. Featuring a recall of polynomial long division. Some history: The quadratic formula (Dating back to antiquity) allows us to solve any quadratic equation. ax2 + bx + c = 0 What about any cubic equation? ax3 + bx2 + cx + d = 0? In the 1540's Cardano produced a \cubic formula." It is too complicated to actually write down here. See today's extra credit. What about any quartic equation? ax4 + bx3 + cx2 + dx + e = 0? A few decades after Cardano, Ferrari produced a \quartic formula" More complicated still than the cubic formula. In the 1820's Galois (age ∼19) proved that there is no general algebraic formula for the solutions to a degree 5 polynomial. In fact there is no purely algebraic way to solve x5 − x − 1 = 0: Galois died in a duel at age 21. This means that, as disheartening as it may feel, we will never get a formulaic solution to a general polynomial equation. The best we can get is tricks that work sometimes. Think of these tricks as analogous to the strategies you use to factor a degree 2 polynomial. Trick 1 If you find one solution, then you can find a factor and reduce to a simpler polynomial equation. Example. 2x2 − x2 − 1 = 0 has x = 1 as a solution. This means that x − 1 MUST divide 2x3 − x2 − 1. Use polynomial long division to write 2x3 − x2 − 1 as (x − 1) · (something). Now find the remaining two roots 1 2 For you: Find all of the solutions to x3 + x2 + x + 1 = 0 given that x = −1 is a solution to this equation.

Sulochanadevi Singhania School, Jekegram, Thane(W), Maharashtra-400606, India. Abstract This paper introduces a new application of differential calculus and integral calculus to solve various forms of quadratic equations. Keywords: quadratic equations, differential calculus, integral calculus, infinitesimal integral calculus, constant of infinity. I. INTRODUCTION This paper is based on the usage of the principles of differential calculus and integral calculus to solve quadratic equations. It is hypothesized that if we use calculus to solve quadratic equations, we will arrive at the same solution that we may get from the quadratic formula method. It is also hypothesized that the quadratic formula can be derived from the quadratic formula. The paper involves the use of differential and integral calculus which takes solving of quadratic equations to the next level. The formulas which we will come across the paper, or use them, are shown in Table 1 under Heading IV. The paper shall be dealt under 2 headings. Heading II will deal with the use of differential calculus in solving quadratic equations while Heading III will deal with the use of integral calculus in quadratic equations, as far as solving of quadratic equations is concerned. Heading V is hugely concerned about the advantages of using calculus to solve quadratic equation. 156 Debjyoti Biswadev Sengupta II. USE OF DIFFERENTIAL CALCULUS TO SOLVE QUADRATIC EQUATIONS To solve quadratic equations, we shall require the use of first order differential calculus only.

Especially when a or c is negative. THE DISCRIMINANT The type of solution to a quadratic equation depends upon what happens under the radical sign (√ ) . Therefore, if you look at the Quadratic Formula above, you’ll see that the “푏2 − 4푎푐 ” part is important. Definition: For the quadratic equation 푎푥2 + 푏푥 + 푐 = 0 , the discriminant is 푏2 − 4푎푐 . If 푏2 − 4푎푐 > 0 and is a perfect square, then 푎푥2 + 푏푥 + 푐 = 0 has two rational solutions. If 푏2 − 4푎푐 > 0 but is not a perfect square, then 푎푥2 + 푏푥 + 푐 = 0 has two irrational solutions. If 푏2 − 4푎푐 = 0 , then 푎푥2 + 푏푥 + 푐 = 0 has one rational solution. If 푏2 − 4푎푐 < 0 , then 푎푥2 + 푏푥 + 푐 = 0 has two complex solutions (involving the imaginary number ).

  • Discriminant & Solutions
    DISCRIMINANT & SOLUTIONS Quadratic equations can be written in the form ��# + �� + � = 0. (To use discriminants, if you have a quadratic (parabolic) equation in the vertex form, � = � � − ℎ # + �, you need to set � = 0 ; multiply through and convert to standard form as above.) ./± /1.234 The quadratic formula gives you the roots (where the function becomes zero); � = . #3 The part under the square root sign is called the discriminant, because it tells you where these roots appear on a graph. There are only three possibilities; the discriminant is positive, zero, or negative. 1: Positive Discriminant. This gives 2 unequal solutions that are real; they pass through the x- axis. They may be rational (if a, b, and c are all rational) or irrational. Examples: ������ ����ℎ: �# − � − 2; � = 1 , � = −1, � = −2. �# − 4�� = 9 > 0. So we have two real roots; {-1, 2}. �������� ����ℎ: − �# − � + 2; � = −1, � = −1, � = 2. �# − 4�� = 9 > 0. So we have two real roots; {-2, 1}; they are different from the above equation because a and c are different. 2: Discriminant = Zero. This means there will be one repeated solution that is a real number. Graphically, it touches the x-axis but doesn’t cross it; although it touches in only one point, there are still two roots at that x value. Examples: ������ ����ℎ: �# − 2� + 1; � = 1 , � = −2, � = 1. �# − 4�� = 0. So we have a repeated root; {1, 1}. �������� ����ℎ: − �# − 2� − 1; � = −1, � = −2, � = −1. �# − 4�� = 0. So we have a repeated root; {-1, -1}; it’s different from the above equation because a and c are different. 3: Negative Discriminant. There are NO real solutions (because the graph doesn’t cross the x- axis), but there are two imaginary roots that are complex conjugates.
