- 2 π + \frac{π}{2}

- \frac{3 π}{2}

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 = - 3 π

= \frac{- 3 π}{2}

Apply the fraction rule:

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

= - \frac{3 π}{2}

- 4 (5)^{2}

5 (1 + s) = - 9 s + 6

4 x^{2} - 8

x^{2} = 7 - x

x^{3} - 3 x^{2} - 2 x
