expand (0.5(x-1)(x+1))/((x+5)(x-5))

expand

\frac{0.5 ( x - 1 ) ( x + 1 )}{( x + 5 ) ( x - 5 )}

\frac{0.5 x ^{2} - 0.5}{x ^{2} - 25}

Solution steps

\frac{0.5 ( x - 1 ) ( x + 1 )}{( x + 5 ) ( x - 5 )}

Expand

(x + 5) (x - 5) : x^{2} - 25

= \frac{0.5 ( x - 1 ) ( x + 1 )}{x ^{2} - 25}

Expand

0.5 (x - 1) (x + 1) : 0.5 x^{2} - 0.5

= \frac{0.5 x ^{2} - 0.5}{x ^{2} - 25}

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

\frac{( s )}{( s ^{2} - 4 ) ^{2}}

2 (a x^{2} + b) + 3

(1, 0, - i) (1 + i, 1, 1 - 2 i) (0, i, 2)

\frac{1 + x}{( 2 + x ) ( 4 - x ^{2} )}
