expand (7x^2-18x-4)/((x+1)^2(x+4))

expand

\frac{7 x ^{2} - 18 x - 4}{( x + 1 ) ^{2} ( x + 4 )}

\frac{7 x ^{2} - 18 x - 4}{x ^{3} + 6 x ^{2} + 9 x + 4}

Solution steps

\frac{7 x ^{2} - 18 x - 4}{( x + 1 ) ^{2} ( x + 4 )}

(x + 1)^{2} = x^{2} + 2 x + 1

= \frac{7 x ^{2} - 18 x - 4}{( x ^{2} + 2 x + 1 ) ( x + 4 )}

Expand

(x^{2} + 2 x + 1) (x + 4) : x^{3} + 6 x^{2} + 9 x + 4

= \frac{7 x ^{2} - 18 x - 4}{x ^{3} + 6 x ^{2} + 9 x + 4}

(e^{\frac{2 y}{5}} + 8 e^{\frac{y}{5}} + 16) (7 - y)

(3 x^{2} y^{2} + cos (x)) \cdot 4 \cdot cos (t)

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

x + 3^{2}

\frac{( s + 3 )}{s ( s ^{2} + 4 s + 85 ) ( s + 10 )}
