expand ((y-1)^2)/4

Solution

expand

\frac{( y - 1 ) ^{2}}{4}

Solution

\frac{y ^{2}}{4} - \frac{y}{2} + \frac{1}{4}

Solution steps

\frac{( y - 1 ) ^{2}}{4}

(y - 1)^{2} = y^{2} - 2 y + 1

= \frac{y ^{2} - 2 y + 1}{4}

Apply the fraction rule:

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

\frac{y ^{2} - 2 y + 1}{4} = \frac{y ^{2}}{4} - \frac{2 y}{4} + \frac{1}{4}

= \frac{y ^{2}}{4} - \frac{2 y}{4} + \frac{1}{4}

Cancel

\frac{2 y}{4} : \frac{y}{2}

= \frac{y ^{2}}{4} - \frac{y}{2} + \frac{1}{4}
