$( - \frac{2}{3}a + \frac{7}{3}b) ^{2} = \\$

$= ( \frac{7}{3} b - \frac{2}{3} a {)}^{2} \\$

$= ( \frac{7}{3} b {)}^{2} - 2 \times \frac{7}{3} b \times \frac{2}{3} a + ( \frac{2}{3} a {)}^{2} \\$

$= \frac{49}{9} {b}^{2} - \frac{28}{9} ab + ( \frac{2}{3} a {)}^{2} \\$

$= \frac{49}{9} {b}^{2} - \frac{28}{9} ab + \frac{4}{9} {a}^{2} \\$

$\\$
