expand (3(x^2-25)(4x^2+4x+1))/(x+2)

expand

\frac{3 ( x ^{2} - 25 ) ( 4 x ^{2} + 4 x + 1 )}{x + 2}

\frac{12 x ^{4} + 12 x ^{3} - 297 x ^{2} - 300 x - 75}{x + 2}

Solution steps

\frac{3 ( x ^{2} - 25 ) ( 4 x ^{2} + 4 x + 1 )}{x + 2}

Expand

3 (x^{2} - 25) (4 x^{2} + 4 x + 1) : 12 x^{4} + 12 x^{3} - 297 x^{2} - 300 x - 75

= \frac{12 x ^{4} + 12 x ^{3} - 297 x ^{2} - 300 x - 75}{x + 2}

- \frac{2}{x \cdot ( x - 0.5 )}

\frac{3 ( e ^{4} - 1 )}{2 e ^{4}}

\frac{20 e ^{- 4 x}}{x ( x ^{2} + 4 x + 20 )}

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

\frac{1}{( a - 2 x ) ^{2} ( b - x )}
