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

expand

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

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

Solution steps

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

Expand

(- x + 3) (x + 3) : 9 - x^{2}

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

A l e f t (A + B)

(e^{2 x} + e^{- 2 x}) (2 e^{2 x} + 2 e^{- 2 x})

\frac{1}{( 1 - x ) ( k x ) ^{0.5}}

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