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) - 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

\frac{3 x + 23}{( x - 4 ) ( x + 1 )}

A (3, 3) B (6, 6) C (10, - 4)

\frac{2 s ^{2} + 2 s + 6}{s ( s + 1 ) ( s + 3 )}

(x + \frac{5}{6}) (x - \frac{7}{6})

(x - 2) l e f t (x + 3)
