Identify the critical values of x. They are the zeros, of -3 and +5.

The intervals in which to check are these:
system%28-infinity%3Cx%3C-3%2C-3%3Cx%3C5%2C5%3Cx%3Cinfinity%29.

YOU pick any x value in each interval to check the solutions for the inequality. The solution values will be OUTSIDE of the two zeros.
