join

- 2 π - \frac{π}{2}

- \frac{5 π}{2}

Decimal Notation

- 7.85398 \dots

Solution steps

- 2 π - \frac{π}{2}

Convert element to fraction:

2 π = \frac{2 π 2}{2}

= - \frac{2 π 2}{2} - \frac{π}{2}

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}{2}

- 2 π 2 - π = - 5 π

= \frac{- 5 π}{2}

Apply the fraction rule:

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

= - \frac{5 π}{2}

\frac{x - 1}{2 x ^{2} + x - 6} \leq 0

- x < - 10

10 x^{2} + 11 x - 6 = 0

10 v^{2} + 23 v + 12

1 + p = 2 p - 1
