expand ((X-11)^2)/2

Solution

expand

\frac{( X - 11 ) ^{2}}{2}

Solution

\frac{X ^{2}}{2} - 11 X + \frac{121}{2}

Solution steps

\frac{( X - 11 ) ^{2}}{2}

(X - 11)^{2} = X^{2} - 22 X + 121

= \frac{X ^{2} - 22 X + 121}{2}

Apply the fraction rule:

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

\frac{X ^{2} - 22 X + 121}{2} = \frac{X ^{2}}{2} - \frac{22 X}{2} + \frac{121}{2}

= \frac{X ^{2}}{2} - \frac{22 X}{2} + \frac{121}{2}

Divide the numbers:

\frac{22}{2} = 11

= \frac{X ^{2}}{2} - 11 X + \frac{121}{2}
