(1-x^2)> 9/25

Solution

(1 - x^{2}) > \frac{9}{25}

Solution

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

+2

Interval Notation

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

Decimal Notation

- 0.8 < x < 0.8

Solution steps

1 - x^{2} > \frac{9}{25}

Move

1

to the right side

- x^{2} > - \frac{16}{25}

Multiply both sides by

- 1

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}
