expand (2s^2-6)/((s^2-4)^2)

expand

\frac{2 s ^{2} - 6}{( s ^{2} - 4 ) ^{2}}

\frac{2 s ^{2} - 6}{s ^{4} - 8 s ^{2} + 16}

Solution steps

\frac{2 s ^{2} - 6}{( s ^{2} - 4 ) ^{2}}

(s^{2} - 4)^{2} = s^{4} - 8 s^{2} + 16

= \frac{2 s ^{2} - 6}{s ^{4} - 8 s ^{2} + 16}

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

A (3, - 4) y B (5.2)

\frac{( 3 s ^{2} + 7 s + 1 )}{( s ( s ^{2} - 2 s + 15 ) )}

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