expand (7x^3+9x^2)/((x^2+8)^2)

expand

\frac{7 x ^{3} + 9 x ^{2}}{( x ^{2} + 8 ) ^{2}}

\frac{7 x ^{3} + 9 x ^{2}}{x ^{4} + 16 x ^{2} + 64}

Solution steps

\frac{7 x ^{3} + 9 x ^{2}}{( x ^{2} + 8 ) ^{2}}

(x^{2} + 8)^{2} = x^{4} + 16 x^{2} + 64

= \frac{7 x ^{3} + 9 x ^{2}}{x ^{4} + 16 x ^{2} + 64}

\frac{15}{( s + 10 ) ( s + 11 )}

y^{4} + (y - 3)^{2}

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

(2 (4, 1, 5) + (2, - 3, 1)) \cdot ((4, 1, 5) - 3 (2, - 3, 1))

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