expand ((x+4)^2)/2

Solution

expand

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

Solution

\frac{x ^{2}}{2} + 4 x + 8

Solution steps

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

(x + 4)^{2} = x^{2} + 8 x + 16

= \frac{x ^{2} + 8 x + 16}{2}

Apply the fraction rule:

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

\frac{x ^{2} + 8 x + 16}{2} = \frac{x ^{2}}{2} + \frac{8 x}{2} + \frac{16}{2}

= \frac{x ^{2}}{2} + \frac{8 x}{2} + \frac{16}{2}

Divide the numbers:

\frac{8}{2} = 4

= \frac{x ^{2}}{2} + 4 x + \frac{16}{2}

Divide the numbers:

\frac{16}{2} = 8

= \frac{x ^{2}}{2} + 4 x + 8
