expand ((x-2)(x+2))/2

expand

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

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

Solution steps

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

Expand

(x - 2) (x + 2) : x^{2} - 4

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

Apply the fraction rule:

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

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

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

Divide the numbers:

\frac{4}{2} = 2

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

\frac{x + 1}{( x - 8 ) ^{2}}

\frac{5 ( 15 105 + 1027 )}{288}

\frac{9 x + 3}{( x - 1 ) ( x + 1 ) ( x + 2 )}

\frac{2 s ^{2} - 6 s + 1}{s ( s - 3 ) ( s + 1 )}

\frac{π ( 18 \cdot 2 ^{\frac{2}{3}} - 14 )}{15}
