3x^2-20<0

Solution

3 x^{2} - 20 < 0

Solution

- \frac{2 5}{3} < x < \frac{2 5}{3}

+2

Interval Notation

(- \frac{2 5}{3}, \frac{2 5}{3})

Decimal Notation

- 2.58198 \dots < x < 2.58198 \dots

Solution steps

3 x^{2} - 20 < 0

Move

20

to the right side

3 x^{2} < 20

Divide both sides by

3

x^{2} < \frac{20}{3}

For

u^{n} < a

, if

n

is even then

- \frac{20}{3} < x < \frac{20}{3}

\frac{20}{3} = \frac{2 5}{3}

- \frac{2 5}{3} < x < \frac{2 5}{3}
