expand (4-2/3 x)^2

Solution

expand

(4 - \frac{2}{3} x)^{2}

Solution

\frac{144 - 48 x + 4 x ^{2}}{9}

Solution steps

(4 - \frac{2}{3} x)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(4 - \frac{2}{3} x)^{2} = 4^{2} - 2 \cdot 4 \cdot \frac{2}{3} x + (\frac{2}{3} x)^{2}

= 4^{2} - 2 \cdot 4 \cdot \frac{2}{3} x + (\frac{2}{3} x)^{2}

Simplify

4^{2} - 2 \cdot 4 \cdot \frac{2}{3} x + (\frac{2}{3} x)^{2} : \frac{144 - 48 x + 4 x ^{2}}{9}

= \frac{144 - 48 x + 4 x ^{2}}{9}
