expand (x+1-a)/((x+1)(x-1))

expand

\frac{x + 1 - a}{( x + 1 ) ( x - 1 )}

\frac{x + 1 - a}{x ^{2} - 1}

Solution steps

\frac{x + 1 - a}{( x + 1 ) ( x - 1 )}

Expand

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

= \frac{x + 1 - a}{x ^{2} - 1}

(- e^{- x}) (2 - sin (2 x))

2 x (y + 1) d x

(200 - e^{2}) \cdot 100

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

(sin^{2} (x) + 2) d x
