expand-(2(5-4sqrt(2)))/7

expand

- \frac{2 ( 5 - 4 2 )}{7}

- \frac{10}{7} + \frac{8 2}{7}

Decimal Notation

0.18767 \dots

Solution steps

- \frac{2 ( 5 - 4 2 )}{7}

Expand

2 (5 - 42) : 10 - 82

= - \frac{10 - 8 2}{7}

Apply the fraction rule:

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

\frac{10 - 8 2}{7} = - (\frac{10}{7}) - (- \frac{8 2}{7})

= - (\frac{10}{7}) - (- \frac{8 2}{7})

Remove parentheses:

(a) = a, - (- a) = a

= - \frac{10}{7} + \frac{8 2}{7}

e^{c o s (x)} (x + 3)

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

(t^{2}) (1 + e^{t})

\frac{y ^{2} ( 8 y ^{\frac{3}{2}} - y ^{3} )}{24}

\frac{( ( x - 25 ) ( x - 30 ) ( x - 35 ) )}{750}
