expand (x^2-1)/((x-2)(x-5))

expand

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

\frac{x ^{2} - 1}{x ^{2} - 7 x + 10}

Solution steps

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

Expand

(x - 2) (x - 5) : x^{2} - 7 x + 10

= \frac{x ^{2} - 1}{x ^{2} - 7 x + 10}

(x + 22) (x - 22)

(x - 4) (x - 2)

(x + 2) e^{\frac{1}{x}}

(3 - x 2)^{2}

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