simplify (x-2+sqrt(2))(x-2-sqrt(2))

simplify

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

Simplify

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

= x^{2} - 4 x + 2

(2 x + \frac{1}{x ^{2}})^{6}

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

(x + 2) (x - 3)

53 (22 + 4)

(2 x) l e f t (2 x + 7)
