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

simplify

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

x^{2} + 42 - 6

Solution steps

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

Distribute parentheses

= xx + x \cdot 2 + x (- 2) - 2 x - 2 \cdot 2 - 2 (- 2) + 2 x + 2 \cdot 2 + 2 (- 2)

Simplify

xx + x \cdot 2 + x (- 2) - 2 x - 2 \cdot 2 - 2 (- 2) + 2 x + 2 \cdot 2 + 2 (- 2) : x^{2} + 42 - 6

= x^{2} + 42 - 6

11 (17 + 122)

\frac{5 x + 13}{( x - 1 ) ( x + 5 )}

\frac{1 - e ^{- 3 s}}{s ( s ^{2} + 2 s + 10 )}

(1 + 2 cos (t)) \cdot (2 sin (t))

((x^{2} + y^{2})^{\frac{1}{2}} + 3 y)^{2}
