Question

Simplify

Answer 1

one way it so multiply top and bottom by \(81x^2\) to clear the complex faction
after that you will factor and cancel

Answer 2

first step give
\[\frac{9x^2-81x}{x^2-81}\]

Answer 3

what do i do now?

Answer 4

stake out common factors. 9x^2 - 81x is the same as 9x(x-9) and x^2-81 is the same as (x+9)(x-9). Cancel the common factors and there's your answer :)

Answer 5

your answers should be 9x/(x+9)
