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

expand

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

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

Solution steps

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

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

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

Expand

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

= \frac{4 x ^{2}}{x ^{3} + x ^{2} - x - 1}

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

\frac{( o - Tw )}{( 1 + r ) ( 1 - T )}
