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

expand

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

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

Solution steps

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

Expand

2 (x^{2} - 2) : 2 x^{2} - 4

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

\frac{5 ( 5 2 - 2 )}{23}

(2 - 2 \cdot e^{- t} - t e^{- t}) u (t)

4 π (r^{3} + 15 r^{2} + 75 r + 125)

e^{t} (sin (t) - cos (t))

\frac{1}{s ^{2} ( s + 4 ) ^{2}}
