expand 3/((a^2-y^2)^2)

expand

\frac{3}{( a ^{2} - y ^{2} ) ^{2}}

\frac{3}{a ^{4} - 2 a ^{2} y ^{2} + y ^{4}}

Solution steps

\frac{3}{( a ^{2} - y ^{2} ) ^{2}}

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

= \frac{3}{a ^{4} - 2 a ^{2} y ^{2} + y ^{4}}

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

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

\frac{1}{( s + x ) ( s + y )}

2 x + 3 \circ (- 2 x + 6)

f (x + 3) d x
