simplify (x^2-8x-20)/(x-10)*(3x)/(x+2)

simplify

\frac{x ^{2} - 8 x - 20}{x - 10} \cdot \frac{3 x}{x + 2}

3 x

Solution steps

\frac{x ^{2} - 8 x - 20}{x - 10} \cdot \frac{3 x}{x + 2}

Cancel

\frac{x ^{2} - 8 x - 20}{x - 10} : x + 2

= (x + 2) \frac{3 x}{x + 2}

Cross-cancel common factor:

x + 2

= 3 x

(9 x - \frac{1}{3 x})^{4}

\frac{50}{2}

(2 a^{3} b^{4})^{4}

\frac{2}{3} \times 9

(3 x^{3} - 2) (3 x^{3} - 1)
