Write each polynomial as the product of two binomials.

Question

What's the answers?
(x - 12)9 + x(x - 12)

x(x + 7) + 9(x + 7)

(x - 10)-9 + 7x(x - 10)

Answer 1

in each case I see a common factor.
I will do the first one, you show me how to do the other two ...

(x-12)9 + x(x-12)
= 9(x-12) + x(x-12), the x-12 is a common factor
= (12-x)(9+x)

all done!
