expand (2x^2)/((x-5)(x+4))

expand

\frac{2 x ^{2}}{( x - 5 ) ( x + 4 )}

\frac{2 x ^{2}}{x ^{2} - x - 20}

Solution steps

\frac{2 x ^{2}}{( x - 5 ) ( x + 4 )}

Expand

(x - 5) (x + 4) : x^{2} - x - 20

= \frac{2 x ^{2}}{x ^{2} - x - 20}

(3 + 2 i)^{2}

\frac{sin ( 2 x ) ( cot ( x ) - csc ( x ) )}{cot ( x ) + csc ( x )}

\frac{2 x ^{5} - x ^{4} + 3 x ^{3} - a x ^{2} + b x - c}{( x - 1 ) ^{3}}

5000 (- 0.125 e^{- 0.125 x} x + 1.75 e^{- 0.125 x})

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