expand-(2x^3+6.6x^2+7.2x)/((x+1)^2)

expand

- \frac{2 x ^{3} + 6.6 x ^{2} + 7.2 x}{( x + 1 ) ^{2}}

- \frac{2 x ^{3} + 6.6 x ^{2} + 7.2 x}{x ^{2} + 2 x + 1}

Solution steps

- \frac{2 x ^{3} + 6.6 x ^{2} + 7.2 x}{( x + 1 ) ^{2}}

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

= - \frac{2 x ^{3} + 6.6 x ^{2} + 7.2 x}{x ^{2} + 2 x + 1}

\frac{4 ( x - 2 ) ^{3}}{625}

\frac{- 3}{( 4.5 - 4 ) ^{2}}

- \frac{2 ( - 2 ln ( x ) + 3 )}{11 x ^{3}}

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

(7 sin (5 x) + 3 cos (7 x)) d x
