Question

The polynomial whose zeroes are -7 and 3 is:

Answer 1

Step-by-step explanation:

let a = -7 and b = 3 are zeros

a +b = -7+3 = -4

ab = -7×3 = -21

x^2 - (a+b)x +ab = 0

x^2 +4x -21 = 0

Answer 2

Step-by-step explanation:

let let alpha be -7 and beta be 3

therefore quadratic equation is equal to

x^2-(alpha + beta)x+(alpha into beta )

therefore equation will be

x^2-(-7+3)x+(-7•3)

x^2+4x-21
