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

expand

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

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

Solution steps

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

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

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

(x \circ x - 6) (x)

\frac{x ^{3} + 4 x ^{2}}{( x + 5 ) ^{3}}

\frac{5 ( s + 2 )}{s ^{2} ( s + 1 ) ( s + 3 )}

(1 - cos (x)) (cot (x) + csc (x) = sin (x))

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