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

expand

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

x^{3} + 4 x^{2} + 2 x - 1

Solution steps

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

Distribute parentheses

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

Simplify

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

= x^{3} + 4 x^{2} + 2 x - 1

(x - 7) (x + 10)

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

(11 + 9 i) 2

2 (\frac{2}{5})^{- 1}

x^{4} + 7 x^{3} + 5 x^{2} - 31 x - 30
