Question

a quadric polynomial whose zeros are. - 3 and 4 is please explain

Answer 1

Hi Friend !!!

Here is ur answer !!!

The quadratic polynomial ,


x²-(sum of roots) x + (product of roots)

= x²- (4-3)x + 4×-3


= x²-x -12


Hope it helps u : )

Answer 2

                      =========================

Given,

Zeroes of a quadratic polynomial = -3 and 4.

Now,

Sum of zeroes = -3 + 4 = 1

Product of zeroes = ( -3 ) × 4 = -12.

The general form of a quadratic equation is :

= x² - ( Sum of zeroes ) x + Product of zeroes

= x² - ( 1 ) x + ( - 12 )

= x² - x - 12.

The required quadratic polynomial is x² - x - 12.
