Question 747404

What is the step by step process to factor this equation using substitution?
(y-2)^2+5(y-2)-36


{{{(y - 2)^2 + 5(y - 2) - 36}}}


{{{x^2 + 5x - 36}}}----- Substituting x for (y - 2)


(x + 9)(x - 4) ------ Factoring trinomial


(y - 2 + 9)(y - 2 - 4) ------ Substituting back (y - 2) for x


{{{highlight_green((y + 7)(y - 6))}}}
