Solution steps

- \frac{2 π}{3} + 2 π

Convert element to fraction:

2 π = \frac{2 π 3}{3}

= - \frac{2 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{- 2 π + 2 π 3}{3}

- 2 π + 2 π 3 = 4 π

= \frac{4 π}{3}

\frac{3 ( x - 12 )}{4} \geq \frac{4 x}{7} - 12

x^{2} + 2 x - 7 = - x^{2} + 4 x + 5

- 3 - 3 i

q^{2} + q = 0

x^{2} + 15 x + 13 = 0
