expand ((z+y)(z-y))/2

expand

\frac{( z + y ) ( z - y )}{2}

\frac{z ^{2}}{2} - \frac{y ^{2}}{2}

Solution steps

\frac{( z + y ) ( z - y )}{2}

Expand

(z + y) (z - y) : z^{2} - y^{2}

= \frac{z ^{2} - y ^{2}}{2}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{z ^{2} - y ^{2}}{2} = \frac{z ^{2}}{2} - \frac{y ^{2}}{2}

= \frac{z ^{2}}{2} - \frac{y ^{2}}{2}

- 2 (4 g - 3 = 30)

2 a - a

e^{2 x} (x - 1)^{2} + e^{x} (x - 1)^{3}

2 a + a

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