expand ((3y-5)^2)/2

Solution

expand

\frac{( 3 y - 5 ) ^{2}}{2}

Solution

\frac{9 y ^{2}}{2} - 15 y + \frac{25}{2}

Solution steps

\frac{( 3 y - 5 ) ^{2}}{2}

(3 y - 5)^{2} = 9 y^{2} - 30 y + 25

= \frac{9 y ^{2} - 30 y + 25}{2}

Apply the fraction rule:

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

\frac{9 y ^{2} - 30 y + 25}{2} = \frac{9 y ^{2}}{2} - \frac{30 y}{2} + \frac{25}{2}

= \frac{9 y ^{2}}{2} - \frac{30 y}{2} + \frac{25}{2}

Divide the numbers:

\frac{30}{2} = 15

= \frac{9 y ^{2}}{2} - 15 y + \frac{25}{2}
