expand (A(2-x^2-y^2))/2

Solution

expand

\frac{A ( 2 - x ^{2} - y ^{2} )}{2}

Solution

A - \frac{A x ^{2}}{2} - \frac{A y ^{2}}{2}

Solution steps

\frac{A ( 2 - x ^{2} - y ^{2} )}{2}

Expand

A (2 - x^{2} - y^{2}) : 2 A - A x^{2} - A y^{2}

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

Apply the fraction rule:

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

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

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

Divide the numbers:

\frac{2}{2} = 1

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