+2

Interval Notation

(- \frac{4}{5}, \frac{4}{5})

Decimal Notation

- 0.8 < x < 0.8

Solution steps

25 x^{2} - 16 < 0

Move

16

to the right side

25 x^{2} < 16

Divide both sides by

25

x^{2} < \frac{16}{25}

For

u^{n} < a

, if

n

is even then

- \frac{16}{25} < x < \frac{16}{25}

\frac{16}{25} = \frac{4}{5}

- \frac{4}{5} < x < \frac{4}{5}

17(2)+44=12+3k+4-k

17 (2) + 44 = 12 + 3 k + 4 - k

\frac{w}{8} < - 4

x + \frac{2}{5} > \frac{2}{3} - 2 x

k^{2} + 4 k + 4 = 0
