expand (-x^3+3x^2(x+2)-1)/((x+2))

expand

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

\frac{2 x ^{3} + 6 x ^{2} - 1}{x + 2}

Solution steps

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

Expand

- x^{3} + 3 x^{2} (x + 2) - 1 : 2 x^{3} + 6 x^{2} - 1

= \frac{2 x ^{3} + 6 x ^{2} - 1}{x + 2}

tan (θ) (cot (θ) + csc (θ))

tan (\frac{x}{2}) + (1 - cos (x)) \cdot cot (x)

(\frac{25 x ^{3}}{3} + 3750 x^{2} + 375000 x + 12500000) \cdot 20

e^{7 - 43} (\frac{1}{2} + 23)

\frac{1}{x ( y - x )}
