expand (t(l^2w^2+r))/(rt+l^2w^2+r)

expand

\frac{t ( l ^{2} w ^{2} + r )}{r t + l ^{2} w ^{2} + r}

\frac{l ^{2} t w ^{2} + t r}{t r + l ^{2} w ^{2} + r}

Solution steps

\frac{t ( l ^{2} w ^{2} + r )}{r t + l ^{2} w ^{2} + r}

Expand

t (l^{2} w^{2} + r) : l^{2} t w^{2} + t r

= \frac{l ^{2} t w ^{2} + t r}{t r + l ^{2} w ^{2} + r}

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

(x - 1 + i y)^{3}

(- 2 sin (t) - t cos (t))^{2}

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

\frac{- 2 x ^{2} - 22 x - 2}{3 ( x - 2 ) ( x + 1 ) ( x - 5 )}
