Question

Find the zeros of the following quadratic polynomial and verify the relationship between the zeros and Coefficient
(1) x²+7x+12
(2) 4x²-4x-3
(3) 2x²-11x+15

Answer 1

Step-by-step explanation:

1). x^2+7x+12

by middle term split

x^2+7x+12

x^2+4x+3x+12

x(x+4)+3(x+4)

(x+4) (x+3)

therefore the zeroes are -3,-4.
