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

expand

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

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

Solution steps

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

Expand

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

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

Apply the fraction rule:

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

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

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

\frac{14 v ( 6 v - 5 )}{3}

\frac{( 11 x ^{4} + 2 ) ^{5}}{2}

(x_{0} + e x_{1} + x_{2} e^{2})^{3}

\frac{d}{d x} ((z) (2 x^{2} + 3 y^{2} + 5 z^{2} - 9))

e^{z} (z + 1)
