expand (2(sqrt(55)-15))/5

expand

\frac{2 ( 55 - 15 )}{5}

\frac{2 11}{5} - 6

Decimal Notation

- 3.03352 \dots

Solution steps

\frac{2 ( 55 - 15 )}{5}

Expand

2 (55 - 15) : 255 - 30

= \frac{2 55 - 30}{5}

Apply the fraction rule:

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

\frac{2 55 - 30}{5} = \frac{2 55}{5} - \frac{30}{5}

= \frac{2 55}{5} - \frac{30}{5}

Cancel

\frac{2 55}{5} : \frac{2 11}{5}

= \frac{2 11}{5} - \frac{30}{5}

Divide the numbers:

\frac{30}{5} = 6

= \frac{2 11}{5} - 6

\frac{2 x ^{2} + 20 x + 45}{( x + 2 ) \cdot ( x + 3 ) \cdot ( x + 4 )}

\frac{61 ( s + 11 )}{5 s ^{3} + 100 s ^{2} + 805 s + 3050}

\frac{20 x + 13}{3 ( 7 x + 5 )}

\frac{8 π ( 36 \cdot 6 ^{\frac{1}{4}} - 1 )}{9}

\frac{x ^{5} + 49}{( x ^{2} - x ) ( x ^{4} + 14 x ^{2} + 49 )}
