expand (2(a+b)(a-b))/(a-b^2)

expand

\frac{2 ( a + b ) ( a - b )}{a - b ^{2}}

\frac{2 a ^{2} - 2 b ^{2}}{a - b ^{2}}

Solution steps

\frac{2 ( a + b ) ( a - b )}{a - b ^{2}}

Expand

2 (a + b) (a - b) : 2 a^{2} - 2 b^{2}

= \frac{2 a ^{2} - 2 b ^{2}}{a - b ^{2}}

- 2 (- 2 sec^{2} (x) + 3 sec^{4} (x))

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

(\frac{a}{6} - \frac{x ^{3}}{5}) (\frac{a}{6} + \frac{x ^{3}}{5})

4 (cos^{2} (2 x) + sin^{2} (2 y))
