expand ((y+2)^2)/4

Solution

expand

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

Solution

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

Solution steps

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

(y + 2)^{2} = y^{2} + 4 y + 4

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

Apply the fraction rule:

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

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

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

Apply rule

\frac{a}{a} = 1

\frac{4}{4} = 1

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

Divide the numbers:

\frac{4}{4} = 1

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