expand-(300(-3x^2-25))/((x^2-25)^3)

expand

- \frac{300 ( - 3 x ^{2} - 25 )}{( x ^{2} - 25 ) ^{3}}

- \frac{- 900 x ^{2} - 7500}{x ^{6} - 75 x ^{4} + 1875 x ^{2} - 15625}

Solution steps

- \frac{300 ( - 3 x ^{2} - 25 )}{( x ^{2} - 25 ) ^{3}}

(x^{2} - 25)^{3} = x^{6} - 75 x^{4} + 1875 x^{2} - 15625

= - \frac{300 ( - 3 x ^{2} - 25 )}{x ^{6} - 75 x ^{4} + 1875 x ^{2} - 15625}

Expand

300 (- 3 x^{2} - 25) : - 900 x^{2} - 7500

= - \frac{- 900 x ^{2} - 7500}{x ^{6} - 75 x ^{4} + 1875 x ^{2} - 15625}

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

(x - 25) (x + 25)

(x - x - 2) (x + x - 2)

β (x, y + 1)

x^{\frac{2}{3}} (2 x - 2)
