-1/(x^2)<0

Solution

- \frac{1}{x ^{2}} < 0

Solution

x < 0 or x > 0

+1

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

- \frac{1}{x ^{2}} < 0

Multiply both sides by

- 1

(reverse the inequality)

(- \frac{1}{x ^{2}}) (- 1) > 0 \cdot (- 1)

Simplify

\frac{1}{x ^{2}} > 0

If

\frac{1}{a} > 0

then

a > 0

x^{2} > 0

For

u^{n} > 0

, if

n

is even then

u < 0

or

u > 0

x < 0 or x > 0
