expand ((x+5)(x-5))/2

expand

\frac{( x + 5 ) ( x - 5 )}{2}

\frac{x ^{2}}{2} - \frac{25}{2}

Solution steps

\frac{( x + 5 ) ( x - 5 )}{2}

Expand

(x + 5) (x - 5) : x^{2} - 25

= \frac{x ^{2} - 25}{2}

Apply the fraction rule:

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

\frac{x ^{2} - 25}{2} = \frac{x ^{2}}{2} - \frac{25}{2}

= \frac{x ^{2}}{2} - \frac{25}{2}

(- x + y = 6,) (2 x + y = 3)

ln (x - 1) \cdot (x - 1)

(- 3 x - 5 ux) (u d x + x d u)

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

(x - y - z)^{5}
