+2

Interval Notation

(- \frac{1}{2}, \frac{1}{2})

Decimal Notation

- 0.70710 \dots < x < 0.70710 \dots

Solution steps

4 x^{2} - 2 < 0

Move

2

to the right side

4 x^{2} < 2

Divide both sides by

4

x^{2} < \frac{1}{2}

For

u^{n} < a

, if

n

is even then

- \frac{1}{2} < x < \frac{1}{2}

Popular Examples

(3-2x)/5 =(4x+1)/3

\frac{3 - 2 x}{5} = \frac{4 x + 1}{3}

x^{4} + 5 x^{2} \geq 36

5.5x=(4.47x-10000)^2

5.5 x = (4.47 x - 10000)^{2}

7 x^{2} = 16

4 + 2 ∣ 4 x - 7 ∣ > 10
