Solution steps

- \frac{9 π}{4} + 2 π

Convert element to fraction:

2 π = \frac{2 π 4}{4}

= - \frac{9 π}{4} + \frac{2 π 4}{4}

Since the denominators are equal, combine the fractions:

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

= \frac{- 9 π + 2 π 4}{4}

- 9 π + 2 π 4 = - π

= \frac{- π}{4}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{π}{4}

- ∣ 3 ∣

\frac{5}{2} + \frac{5}{3}

\frac{5 x}{3 x ^{2}} - \frac{7}{6 x}

- (3 x - 2)^{2} + 3 (3 x - 2) + 10

(- 3 + 3 i) + (7 - 2 i)
