simplify (3x^2-15x)/(x^2-4x-5)

simplify

\frac{3 x ^{2} - 15 x}{x ^{2} - 4 x - 5}

\frac{3 x}{x + 1}

Solution steps

\frac{3 x ^{2} - 15 x}{x ^{2} - 4 x - 5}

Factor

3 x^{2} - 15 x : 3 x (x - 5)

= \frac{3 x ( x - 5 )}{x ^{2} - 4 x - 5}

Factor

x^{2} - 4 x - 5 : (x + 1) (x - 5)

= \frac{3 x ( x - 5 )}{( x + 1 ) ( x - 5 )}

Cancel the common factor:

x - 5

= \frac{3 x}{x + 1}

1 + i + i^{2}

(i \cdot 5)^{2} \cdot 3

(2 n + 2)^{2}

+ \frac{8 a ^{3} - 27}{9 - 12 a + 4 a ^{2}}

0.00 9^{2}
