Solution steps

\frac{π}{2} + 2

Convert element to fraction:

2 = \frac{2 \cdot 2}{2}

= \frac{π}{2} + \frac{2 \cdot 2}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{π + 2 \cdot 2}{2}

Multiply the numbers:

2 \cdot 2 = 4

= \frac{π + 4}{2}

3 x + 1 = x^{2} + 7 x + 5

(2 x - 3)^{2} - 4 (2 x - 3) - 5

x^{2} - 4 x + 3 > x

472

x + 2 \geq 0
