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

expand

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

6 - \frac{2}{15}

Decimal Notation

5.48360 \dots

Solution steps

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

Expand

2 (45 - 15) : 90 - 215

= \frac{90 - 2 15}{15}

Apply the fraction rule:

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

\frac{90 - 2 15}{15} = \frac{90}{15} - \frac{2 15}{15}

= \frac{90}{15} - \frac{2 15}{15}

Divide the numbers:

\frac{90}{15} = 6

= 6 - \frac{2 15}{15}

Cancel

\frac{2 15}{15} : \frac{2}{15}

= 6 - \frac{2}{15}

sin (2 (t + π))

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

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

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

\frac{( 1 - 2 x ) π}{x - 1}
