Solution

- 7 \leq x \leq - 3 or x > 0

+1

Interval Notation

[- 7, - 3] \cup (0, \infty)

Solution steps

x + 10 \geq - \frac{21}{x}

Rewrite in standard form

\frac{x ^{2} + 10 x + 21}{x} \geq 0

Factor

\frac{x ^{2} + 10 x + 21}{x} : \frac{( x + 3 ) ( x + 7 )}{x}

\frac{( x + 3 ) ( x + 7 )}{x} \geq 0

Identify the intervals

- 7 \leq x \leq - 3 or x > 0
