expand (2(x+1)(x-1))/(x+3)

expand

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

\frac{2 x ^{2} - 2}{x + 3}

Solution steps

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

Expand

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

= \frac{2 x ^{2} - 2}{x + 3}

(7 x - 4) e^{4 x}

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

\frac{d}{d v} ((p) (p + \frac{8.2}{v ^{2}}) (v - 5.4))

e^{k t} cosh (2 k t) - H (t - a) (t - 2)
