simplify (sqrt(2)-1)/(sqrt(2)+1)+4/(sqrt(2))

simplify

\frac{2 - 1}{2 + 1} + \frac{4}{2}

3

Solution steps

\frac{2 - 1}{2 + 1} + \frac{4}{2}

\frac{2 - 1}{2 + 1} = 3 - 22

\frac{4}{2} = 2 \cdot 2

= 3 - 22 + 2 \cdot 2

Add similar elements:

- 22 + 2 \cdot 2 = 0

= 3

\frac{x ^{4}}{x ^{4}}

\frac{- 2}{- 10}

\frac{d + 5}{3} = \frac{d - 1}{9}

1 - \frac{1}{5} \times \frac{1}{5} \times \frac{1}{5}

1 x^{2} + 4 x + 2 = 0
