Tyrone claims that the first step to simplify this expression is to raise the numerator and denominator to the third power. alisha claims that the first step to simplify is to apply the quotient of powers. who is correct? explain.

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
