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

expand

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

x^{4} + x^{3} + x^{2} - x - 2

Solution steps

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

Distribute parentheses

= x x^{3} + xx + x (- 2) + 1 \cdot x^{3} + 1 \cdot x + 1 \cdot (- 2)

Simplify

x x^{3} + xx + x (- 2) + 1 \cdot x^{3} + 1 \cdot x + 1 \cdot (- 2) : x^{4} + x^{3} + x^{2} - x - 2

= x^{4} + x^{3} + x^{2} - x - 2

y^{^{'}} - \frac{6 y}{x} = (\frac{y}{x ^{2}})^{4}

\int \frac{( x + 3 ) ^{4}}{x} d x

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

\int \frac{1}{5 - 8 x - x ^{2}} d x

\int (e^{3 x} + e^{- 3 x})^{2} d x
