Question

The sum of zeros = -3; the product of zeros = -4.Obtain a quadratic polynomial with the given condition.

Answer 1

Solution :

_________________________

If m , n are two zeroes of Quadratic

polynomial then

Quadratic polynomial

p(x) = x² - ( m + n )x + mn
__________________________

Here ,

m + n = -3 ,

mn = -4 ,

Required Quadratic polynomial

= x² - ( -3 )x + ( -4 )

= x² + 3x - 4
