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

expand

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

\frac{x ^{2} - 1}{4 x ^{2} + 2 x}

Solution steps

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

Expand

2 x (2 x + 1) : 4 x^{2} + 2 x

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

Expand

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

= \frac{x ^{2} - 1}{4 x ^{2} + 2 x}

(m^{2} - n^{2})^{2} + 2 mn

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

(2, - 7) y (- 4, 11)

e^{y} (y - 1)

(e^{\frac{y}{4}} + 6)^{2}
