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

expand

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

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

Solution steps

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

Expand

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

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

sin (x + \frac{π}{4})

(c - d) (e + f)

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

\frac{2 cos ( z )}{( z - 3 ) ^{3}}

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