expand-(3(2-sqrt(11)))/7

expand

- \frac{3 ( 2 - 11 )}{7}

- \frac{6}{7} + \frac{3 11}{7}

Solution steps

- \frac{3 ( 2 - 11 )}{7}

Expand

3 (2 - 11) : 6 - 311

= - \frac{6 - 3 11}{7}

Apply the fraction rule:

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

\frac{6 - 3 11}{7} = - (\frac{6}{7}) - (- \frac{3 11}{7})

= - (\frac{6}{7}) - (- \frac{3 11}{7})

Remove parentheses:

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

= - \frac{6}{7} + \frac{3 11}{7}

\frac{d}{d y} ((x) (84 x - x^{2}))

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

\frac{( - 1 ) ^{n + 1} ( n - 1 ) ( n + 2 )}{n}

5 (\cdot + 2 - 8 + \cdot = - 16)

\frac{( 3 x + 12 y ) ( 3 x + 28 y )}{16}
