expand (3(sqrt(15)-5))/(10)

expand

\frac{3 ( 15 - 5 )}{10}

\frac{3 3}{2 5} - \frac{3}{2}

Decimal Notation

- 0.33810 \dots

Solution steps

\frac{3 ( 15 - 5 )}{10}

Expand

3 (15 - 5) : 315 - 15

= \frac{3 15 - 15}{10}

Apply the fraction rule:

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

\frac{3 15 - 15}{10} = \frac{3 15}{10} - \frac{15}{10}

= \frac{3 15}{10} - \frac{15}{10}

Cancel

\frac{3 15}{10} : \frac{3 3}{2 5}

= \frac{3 3}{2 5} - \frac{15}{10}

Cancel

\frac{15}{10} : \frac{3}{2}

= \frac{3 3}{2 5} - \frac{3}{2}

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

\frac{f ( 2 + h ) - 3}{h}

(e^{x} - x) + (e^{x} - x)^{2}

\frac{x}{( x ^{2} + 1 ) ( t x + 1 )}

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