simplify (x-1+sqrt(10))(x-1-sqrt(10))

simplify

(x - 1 + 10) (x - 1 - 10)

x^{2} - 2 x - 9

Solution steps

(x - 1 + 10) (x - 1 - 10)

Distribute parentheses

= xx + x (- 1) + x (- 10) - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot (- 10) + 10 x + 10 (- 1) + 10 (- 10)

Simplify

xx + x (- 1) + x (- 10) - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot (- 10) + 10 x + 10 (- 1) + 10 (- 10) : x^{2} - 2 x - 9

= x^{2} - 2 x - 9
