Answer 1

Answer:

since the zeros are -2,7

the factors are (x+2)(x-7)

the polynomial is x²-5x-14

Answer 2

Answer:

x²-5x-14

Step-by-step explanation:

let alpha= -2 and beta= 7

formula for calculating quadratic equation....

= x²- (alpha + beta)x +aplha × beta

putting values of alpha and beta....

= x²-(-2 +7)x + -2×7

= x² -5x -14
