---------------------
Equations don't have answers. Questions have answers, equations have solutions.
---
What equation? I don't see an equal sign. equal, equate, equation.
---
Equations are not factored, they're solved.
---
(9x-90)/(x^2-8x-20
That can be reduced, or simplified.
Factor the numerator first.
That'll give a big clue on how to factor the denominator.
