\frac{1}{2} (\frac{2}{3})^{2} - 4 (\frac{2}{3}) + 6

Apply rule:

(a) = a

(\frac{2}{3}) = \frac{2}{3}

= \frac{1}{2} (\frac{2}{3})^{2} - 4 \cdot \frac{2}{3} + 6

\frac{1}{2} (\frac{2}{3})^{2} = \frac{2}{9}

4 \cdot \frac{2}{3} = \frac{8}{3}

= \frac{2}{9} - \frac{8}{3} + 6

\frac{2}{9} - \frac{8}{3} + 6 = \frac{32}{9}

= \frac{32}{9}

f a c t or x^{3} + 2 x^{2} - 9 x - 18

4 x - 5 + 2 x = 3 x - 8 + 2 x

6 x + 18 = - 30

3 ∣ 2 x - 1 ∣ = 9

u^{2} - 13 = - 36
