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

simplify

(x - 2 - 2) \cdot (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

(2 + 2) 4

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

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

e^{2 x} + e^{- 2 x} (2 e^{2 x} + 2 e^{- 2 x})
