expand 1/((x^2-a^2)^2)

expand

\frac{1}{( x ^{2} - a ^{2} ) ^{2}}

\frac{1}{x ^{4} - 2 a ^{2} x ^{2} + a ^{4}}

Solution steps

\frac{1}{( x ^{2} - a ^{2} ) ^{2}}

(x^{2} - a^{2})^{2} = x^{4} - 2 a^{2} x^{2} + a^{4}

= \frac{1}{x ^{4} - 2 a ^{2} x ^{2} + a ^{4}}

\frac{2 k ( k + 1 ) + k + 1}{k + 1}

2 (\frac{2}{2} + \frac{4}{5})

m (12, - 23) n (- 34, 32)

20 (15 e^{- \frac{2 x}{5}} + 1)

\frac{3 x ^{2} - 6 x + 5}{( x - 1 ) ^{2}}
