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

\[\frac{3x^2}{x^21}/\frac{9x}{x^2+2x+1} \]Is the above the problem expression?

The first fraction that you put goes above the second.

Well "/", although small, is a division sign.\[\left(\frac{3x^2}{x^21}/\frac{9x}{x^2+2x+1}\right)=\left(\frac{3x^2}{x^21}*\frac{x^2+2x+1}{9x}\right) \]Try factoring the expressions containing x^2. Also, 3x^2/9x will simplify.

The above is correct except for the 3x. Can you simplify the following.\[\frac{3x^2}{9x} \]

Ohh would the 3x go on the bottom with the denominator? x^2

\[\frac{3x^2}{9x}=\frac{x}{3} \]Sorry, I had to leave the computer for a few minutes.

Congratulations.\[\frac{x (x+1)}{3 (x1)} \]is correct.
