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

Solution

expand

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

Solution

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

Solution steps

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

Expand

(x + 1)^{2} : x^{2} + 2 x + 1

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

Distribute parentheses

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

Simplify

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

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