Question

can someone tell me what the simplified form of this equation is???

Answer 1

3x^2/x^2-1/9x/x^2+2x+1

Answer 2

the answer choices are
x(x-1)/3(x+1)
x(x+1)/3(x-1)
3x(x+1)/(x-1)
(x-1)/3x(x+1)

Answer 3

mathhater94 can you elaborate on the question?
Maybe with brackets

Answer 4

ok.. so its

\[\frac{\frac{3x^2}{x^2 -1}}{\frac{9x}{x^2 + 2x + 1}}\]

so dividing by a fraction requires you to find the reciprocal of the denominator and multiply

so its

\[\frac{3x^2}{x^2 -1} \times \frac{x^2 + 2x + 1}{9x}\]

but before multiplying factor some of the terms so you can see the common factors that cancel

\[\frac{3x(x)}{(x +1)(x-1)} \times \frac{(x +1)^2}{3x(3)}\]

cancel common factors leaves

\[\frac{x}{(x -1)} \times \frac{(x + 1)}{3}\]

multiply it out for your answer.
