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

Solution

expand

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

Solution

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

Solution steps

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

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

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

Apply the fraction rule:

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

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

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

Divide the numbers:

\frac{4}{2} = 2

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