How do I factor 64+X+ y 8

Howdy Hey There!

You must have input your numbers incorrectly into the question, as your number posted is not factorable. Is there an exponent? If you comment on this question with a corrected expression I will gladly edit my answer :)

Have a good day.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
