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

expand

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

\frac{- x ^{3} + 3 x}{- 1 + y}

Solution steps

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

Expand

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

= \frac{- x ^{3} + 3 x}{- 1 + y}

\frac{- 4 x + 21}{3 ( 7 - x ) ^{\frac{2}{3}}}

(x^{2} + (y - 1)^{2} + x^{2} + (y + 1)^{2})^{2}

2 (e^{4} - 1)

(2 - x + 3) (2 + x + 3)

(4 - x - 2)^{2}
