expand (-2x^2-20x+20)/((x^2+10)^2)

expand

\frac{- 2 x ^{2} - 20 x + 20}{( x ^{2} + 10 ) ^{2}}

\frac{- 2 x ^{2} - 20 x + 20}{x ^{4} + 20 x ^{2} + 100}

Solution steps

\frac{- 2 x ^{2} - 20 x + 20}{( x ^{2} + 10 ) ^{2}}

(x^{2} + 10)^{2} = x^{4} + 20 x^{2} + 100

= \frac{- 2 x ^{2} - 20 x + 20}{x ^{4} + 20 x ^{2} + 100}

- 2 (1 - 3)

sec (t) (tan (t) + sec (t)) d t

e^{x^{3}} (sin (x) + cos (x))

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