expand (2(45-2sqrt(15)))/(15)

expand

\frac{2 ( 45 - 2 15 )}{15}

6 - \frac{4}{15}

Decimal Notation

4.96720 \dots

Solution steps

\frac{2 ( 45 - 2 15 )}{15}

Expand

2 (45 - 215) : 90 - 415

= \frac{90 - 4 15}{15}

Apply the fraction rule:

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

\frac{90 - 4 15}{15} = \frac{90}{15} - \frac{4 15}{15}

= \frac{90}{15} - \frac{4 15}{15}

Divide the numbers:

\frac{90}{15} = 6

= 6 - \frac{4 15}{15}

Cancel

\frac{4 15}{15} : \frac{4}{15}

= 6 - \frac{4}{15}

\frac{( x ^{2} + 3 x + 5 ) n + x ^{2} ( x + 3 ) 2 + 3}{x ^{2} + 3 x + 4}

\frac{( w - 20 ) ( 380 - w )}{2}

1 - (\frac{1600}{( s + 4 ) ( s ^{2} + 40 s + 80 )})
