Quadratic Polynomial with Given Sum and Product of ZeroesIntroduction:In this problem, we are given the sum and product of the zeroes of a quadratic polynomial and we need to find the polynomial. The general form of a quadratic polynomial is ax^2 + bx + c, where a, b, and c are constants.
Given Information:- Sum of zeroes = S
- Product of zeroes = P
Formula:- Sum of zeroes (S) = -b/a
- Product of zeroes (P) = c/a
Steps to Find the Quadratic Polynomial:- Step 1: Use the formulas to create two equations
- Step 2: Substitute the given values of S and P into the equations
- Step 3: Solve the equations simultaneously to find the values of a, b, and c
- Step 4: Substitute the values of a, b, and c into the general form of the quadratic polynomial
Example:Let's consider an example where the sum of zeroes is 5 and the product of zeroes is 6.
Given:
- Sum of zeroes (S) = 5
- Product of zeroes (P) = 6
Using the formulas:
- -b/a = 5
- c/a = 6
Solving the equations:
- From the first equation, we get b = -5a
- Substitute b = -5a into the second equation: -5a^2 = 6a
Solving for a, we get a = -3/5
Substitute a back into b = -5a, we get b = 3
Substitute a and b into the general form, we get the quadratic polynomial: -3/5x^2 + 3x + 6
Therefore, the quadratic polynomial with the sum of zeroes as 5 and the product of zeroes as 6 is -3/5x^2 + 3x + 6.
