Solution steps

- 2 π - \frac{π}{4}

Convert element to fraction:

2 π = \frac{2 π 4}{4}

= - \frac{2 π 4}{4} - \frac{π}{4}

Since the denominators are equal, combine the fractions:

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

= \frac{- 2 π 4 - π}{4}

- 2 π 4 - π = - 9 π

= \frac{- 9 π}{4}

Apply the fraction rule:

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

= - \frac{9 π}{4}
