Solution

x \leq - \frac{5}{2} or x \geq \frac{5}{2}

+2

Interval Notation

(- \infty, - \frac{5}{2}] \cup [\frac{5}{2}, \infty)

Decimal Notation

x \leq - 2.5 or x \geq 2.5

Solution steps

4 x^{2} - 25 \geq 0

Move

25

to the right side

4 x^{2} \geq 25

Divide both sides by

4

x^{2} \geq \frac{25}{4}

For

u^{n} \geq a

, if

n

is even then

x \leq - \frac{25}{4} or x \geq \frac{25}{4}

\frac{25}{4} = \frac{5}{2}

x \leq - \frac{5}{2} or x \geq \frac{5}{2}
