Answer 1

I tried to eliminate the choices, but I kept messing up. I just need help figuring out how to solve

Answer 2

\[\frac{3x^2}{x^2-1}/\frac{9x}{x^2+2x+1} \]Is the above the problem expression?

Answer 3

The first fraction that you put goes above the second.

Answer 4

Oh I read that awrong. You're right!

Answer 5

Well "/", although small, is a division sign.\[\left(\frac{3x^2}{x^2-1}/\frac{9x}{x^2+2x+1}\right)=\left(\frac{3x^2}{x^2-1}*\frac{x^2+2x+1}{9x}\right) \]Try factoring the expressions containing x^2. Also, 3x^2/9x will simplify.
