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

Solution

expand

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

Solution

\frac{y ^{2}}{3} - 2 y + 3

Solution steps

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

(y - 3)^{2} = y^{2} - 6 y + 9

= \frac{y ^{2} - 6 y + 9}{3}

Apply the fraction rule:

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

\frac{y ^{2} - 6 y + 9}{3} = \frac{y ^{2}}{3} - \frac{6 y}{3} + \frac{9}{3}

= \frac{y ^{2}}{3} - \frac{6 y}{3} + \frac{9}{3}

Divide the numbers:

\frac{6}{3} = 2

= \frac{y ^{2}}{3} - 2 y + \frac{9}{3}

Divide the numbers:

\frac{9}{3} = 3

= \frac{y ^{2}}{3} - 2 y + 3
