Best ResponseYou've already chosen the best response.0We start with: \[\frac{ x^2  3x  54 }{ x^2  18x + 81 }\times \frac{ x^2 + 12x + 36 }{ x + 6 }\] Factoring each of these polynomial expressions gets us the following: \[\frac{ (x9)(x+6)(x+6)(x+6) }{ (x9)(x9)(x+6) }\] which quickly condenses to: \[\frac{ (x9)(x+6)^3 }{ (x9)^2(x+6) }\] Because of all the common factors in the numerator and denominator, we can reduce this further to our final and most reduced form: \[\frac{ (x+6)^2 }{ x9 }\] which is our final answer.
