expand (x+2/3)^2

Solution

expand

(x + \frac{2}{3})^{2}

Solution

\frac{9 x ^{2} + 12 x + 4}{9}

Solution steps

(x + \frac{2}{3})^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

x^{2} + 2 x \frac{2}{3} + (\frac{2}{3})^{2} : \frac{9 x ^{2} + 12 x + 4}{9}

= \frac{9 x ^{2} + 12 x + 4}{9}
