Question

-7 and -4 the quadratic equation is?
Thank you in advance :)

Answer 1

This makes no sense.

do you mean

(x+7)(x+4)=0 where the roots are -4,-7?

FOIL it out.

Answer 2

x=-7 and x=-4
x+7=0 and x+4=0

(x+7)(x+4) = x^2 + 4x + 7x +28

the equation would be x^2 + 11x + 28

Answer 3

correct
