expand (x^4-12x)/((x^2-4)^2)

expand

\frac{x ^{4} - 12 x}{( x ^{2} - 4 ) ^{2}}

\frac{x ^{4} - 12 x}{x ^{4} - 8 x ^{2} + 16}

Solution steps

\frac{x ^{4} - 12 x}{( x ^{2} - 4 ) ^{2}}

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

= \frac{x ^{4} - 12 x}{x ^{4} - 8 x ^{2} + 16}

18 sin^{9 x} (x) (ln (sin (x)) + x cot (x))

(x + 7) (x - 7)

e^{x} (cos (x) - sin (x))

(x - 3) (x^{2} - 10 - 26)

(2 x^{\frac{1}{4}} + 5) (2 x^{\frac{1}{4}} - 5)
