expand (3x(x-5))/((x+2)(x+1))

expand

\frac{3 x ( x - 5 )}{( x + 2 ) ( x + 1 )}

\frac{3 x ^{2} - 15 x}{x ^{2} + 3 x + 2}

Solution steps

\frac{3 x ( x - 5 )}{( x + 2 ) ( x + 1 )}

Expand

(x + 2) (x + 1) : x^{2} + 3 x + 2

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

Expand

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

= \frac{3 x ^{2} - 15 x}{x ^{2} + 3 x + 2}

(e^{5 m} - f^{n})^{2}

\frac{2 + 3 x}{( x + 4 ) ( x ^{2} - 5 x + 6 )}

\frac{( 1 - j )}{( 1 + j ) ^{2}}

\frac{1}{2 ( x + h )}

- 5 (e - 4)
