expand (2(x+9)(x+1))/((x+4)(x-2))

expand

\frac{2 ( x + 9 ) ( x + 1 )}{( x + 4 ) ( x - 2 )}

\frac{2 x ^{2} + 20 x + 18}{x ^{2} + 2 x - 8}

Solution steps

\frac{2 ( x + 9 ) ( x + 1 )}{( x + 4 ) ( x - 2 )}

Expand

(x + 4) (x - 2) : x^{2} + 2 x - 8

= \frac{2 ( x + 9 ) ( x + 1 )}{x ^{2} + 2 x - 8}

Expand

2 (x + 9) (x + 1) : 2 x^{2} + 20 x + 18

= \frac{2 x ^{2} + 20 x + 18}{x ^{2} + 2 x - 8}

x (x - 2 y)

\frac{d ^{3}}{d x ^{3}} ((y) (x^{10} - sec (x)))

\frac{1}{( 1 - 5 x ) ^{3}}
