expand (2(4x+3))/((x-3)(x+7))

expand

\frac{2 ( 4 x + 3 )}{( x - 3 ) ( x + 7 )}

\frac{8 x + 6}{x ^{2} + 4 x - 21}

Solution steps

\frac{2 ( 4 x + 3 )}{( x - 3 ) ( x + 7 )}

Expand

(x - 3) (x + 7) : x^{2} + 4 x - 21

= \frac{2 ( 4 x + 3 )}{x ^{2} + 4 x - 21}

Expand

2 (4 x + 3) : 8 x + 6

= \frac{8 x + 6}{x ^{2} + 4 x - 21}

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

\frac{3 x ^{2}}{( p - x ) ^{2}}

\frac{e ^{(a + x) t} - e ^{a t}}{x}

4 (x^{2} - 4 x + 3)^{2}

\frac{1}{3 ( 2 t ^{2} - 1 )}
