expand (2(2sqrt(2)-1))/3

expand

\frac{2 ( 2 2 - 1 )}{3}

\frac{4 2}{3} - \frac{2}{3}

Decimal Notation

1.21895 \dots

Solution steps

\frac{2 ( 2 2 - 1 )}{3}

Expand

2 (22 - 1) : 42 - 2

= \frac{4 2 - 2}{3}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{4 2 - 2}{3} = \frac{4 2}{3} - \frac{2}{3}

= \frac{4 2}{3} - \frac{2}{3}

(x + 8) (x - 8)

tan (3 x) (tan (x) - 1)

\frac{z - 1}{( z + 1 ) ( 3 z - 1 )}

2 (5 + 3)

tan (\frac{π}{8})
