expand (x-2-sqrt(2))(x-2+sqrt(2))

expand

(x - 2 - 2) (x - 2 + 2)

x^{2} - 4 x + 2

Solution steps

(x - 2 - 2) (x - 2 + 2)

Distribute parentheses

= xx + x (- 2) + x 2 - 2 x - 2 (- 2) - 22 - 2 x - 2 (- 2) - 22

Simplify

xx + x (- 2) + x 2 - 2 x - 2 (- 2) - 22 - 2 x - 2 (- 2) - 22 : x^{2} - 4 x + 2

= x^{2} - 4 x + 2

(1 + x) \cdot x

\frac{3}{( x ^{2} + 4 ) ( x ^{2} + 9 )}

3 (7 + 8)

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

- 5 (- v + 6 w + (- \frac{1}{2}) w)
