Question

find the sum and product of zeroes of each polynomial:

x^2 + 7x + 10

5x^2 - 7x + 2

x^2 - 3

3x^2 - 4x - 4

Answer 1

Answer:

If the coefficient of x2 is 1, that is, if the polynomial is of the following form p(x): x2+ex+f, then the sum and product of the zeroes are simply: S= −e/1= −e and P= f/1= f. Important Notes: The quadratic formula to find the roots of a quadratic equation p(x):ax2+bx+c is −b±√b2−4ac2a − b ± b 2 − 4 a c 2 a .
