Question 249100
You're doing great until you reach the last step. You CANNOT reduce {{{(w^2+17w)/(w^2-81)}}} to {{{(17w)/(-81)}}} as the numerator and denominator have no common factor. Since you can't reduce at all, your final answer will be {{{(w^2+17w)/(w^2-81)}}}



So {{{(8w)/((w+9)(w-9))+w/(w-9)=(w^2+17w)/(w^2-81)}}}
