expand ((3+sqrt(5))y)/2

expand

\frac{( 3 + 5 ) y}{2}

\frac{3 y}{2} + \frac{5 y}{2}

Solution steps

\frac{( 3 + 5 ) y}{2}

Expand

(3 + 5) y : 3 y + 5 y

= \frac{3 y + 5 y}{2}

Apply the fraction rule:

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

\frac{3 y + 5 y}{2} = \frac{3 y}{2} + \frac{5 y}{2}

= \frac{3 y}{2} + \frac{5 y}{2}

(\frac{1}{( s + 1 ) ^{2}} + 2) \cdot (- (s + 1))

\frac{x + 4}{( 3 x + 2 ) ( x - 8 )}

\frac{( 3 x + 4 ) ( x - 9 )}{( x - 2 ) ( x + 2 )}

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

\frac{4}{( s + 2 ) ^{2}}
