expand (-3x^2+2x+12)/((x-2)(x+2)(x+1))

expand

\frac{- 3 x ^{2} + 2 x + 12}{( x - 2 ) ( x + 2 ) ( x + 1 )}

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

Solution steps

\frac{- 3 x ^{2} + 2 x + 12}{( x - 2 ) ( x + 2 ) ( x + 1 )}

Expand

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

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

2 x (1 - ln (x))

(x + 1 + i)^{4}

\frac{3 ( - \frac{7}{8} ) ^{n} + 5}{17}

(x^{4} - 9) \frac{d y}{d x} + x^{3} y

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