expand (4-x^2)/2

Solution

expand

\frac{4 - x ^{2}}{2}

Solution

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

Solution steps

\frac{4 - x ^{2}}{2}

Apply the fraction rule:

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

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

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

Divide the numbers:

\frac{4}{2} = 2

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

Rewrite in standard form

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