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

expand

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

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

Solution steps

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

Expand

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

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

\frac{x ( x + 1 )}{t}

\frac{5}{x ( x ^{2} - 16 )}

e^{(t - 1)^{2}}

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

2 (4 e^{- 2 x} x^{3} - 2 e^{- 2 x} x^{4})
