expand (3(sqrt(5)-1))/2

expand

\frac{3 ( 5 - 1 )}{2}

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

Decimal Notation

1.85410 \dots

Solution steps

\frac{3 ( 5 - 1 )}{2}

Expand

3 (5 - 1) : 35 - 3

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

Apply the fraction rule:

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

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

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

\frac{( 4 - t ^{2} ) ( 5 t - 3 )}{( 4 t + 3 ) ( 5 t + 1 )}

M (3, 6) y N (3, - 6)

\frac{( 6 x ^{2} - 2 )}{( 1 + x ^{2} ) ^{3}}

\frac{20 - 23}{\frac{12.55}{53}}

\frac{1}{( cos ( x ) \cdot ( 1 - x ) )}
