Solution steps

- \frac{4 π}{3} + 2 π

Convert element to fraction:

2 π = \frac{2 π 3}{3}

= - \frac{4 π}{3} + \frac{2 π 3}{3}

Since the denominators are equal, combine the fractions:

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

= \frac{- 4 π + 2 π 3}{3}

- 4 π + 2 π 3 = 2 π

= \frac{2 π}{3}

\frac{4}{3} \div \frac{8}{9}

\frac{8 + 3}{6}

x y - 2 x y + 3 x^{2} y - 4 x y^{2} + 2 x y^{2}

x^{2} (x - 2) + x (x - 2)^{2}

3 (x - 1)^{2} - 4 (x - 1) - 12
