simplify (4x)/(x-1)*(x^2-1)/(3x+3)

simplify

\frac{4 x}{x - 1} \cdot \frac{x ^{2} - 1}{3 x + 3}

\frac{4 x}{3}

Solution steps

\frac{4 x}{x - 1} \cdot \frac{x ^{2} - 1}{3 x + 3}

Cancel

\frac{x ^{2} - 1}{3 x + 3} : \frac{x - 1}{3}

= \frac{4 x}{x - 1} \cdot \frac{x - 1}{3}

Cross-cancel common factor:

x - 1

= \frac{4 x}{3}

\frac{( x ^{2} - 1 )}{x - 1}

\frac{r + 6}{3 r - 6} + \frac{r + 1}{3 r - 6}

- \frac{1}{2} \cdot (- 4)

\frac{x ^{2} - 16}{x ^{2} - 8 x + 16}

(m - n^{2}) (am - an - 3)
