expand ((x+1)^2)/2

Solution

expand

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

Solution

\frac{x ^{2}}{2} + x + \frac{1}{2}

Solution steps

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

(x + 1)^{2} = x^{2} + 2 x + 1

= \frac{x ^{2} + 2 x + 1}{2}

Apply the fraction rule:

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

\frac{x ^{2} + 2 x + 1}{2} = \frac{x ^{2}}{2} + \frac{2 x}{2} + \frac{1}{2}

= \frac{x ^{2}}{2} + \frac{2 x}{2} + \frac{1}{2}

Divide the numbers:

\frac{2}{2} = 1

= \frac{x ^{2}}{2} + x + \frac{1}{2}
