Question

The expression y² – 10y + 24 has a factor of y – 4. What is another factor of y² – 10y + 24?

Answer 1

(y-4) and (y-6) are the two factors

use foil backwards

FOIL= first times first, outside times outside, inside times inside and last times last

F = y*y=y^2

O=y*(-6)=-6y

I=-4*y=-4y

L=(-4)*(-6)=24

combine to get your original equation

Answer 2

x-6 is also one. Happy to help!!
