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

expand

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

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

Solution steps

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

Distribute parentheses

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

Simplify

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

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

16 x^{2} + x - 15

x^{2} - y^{6}

5 \div \frac{3}{8}

4 r^{- 1} + \frac{3}{r}

(u + v) (u - v)
