(x-1)/(x^2-9)<0

Solution

\frac{x - 1}{x ^{2} - 9} < 0

Solution

x < - 3 or 1 < x < 3

+1

Interval Notation

(- \infty, - 3) \cup (1, 3)

Solution steps

\frac{x - 1}{x ^{2} - 9} < 0

Factor

\frac{x - 1}{x ^{2} - 9} : \frac{x - 1}{( x + 3 ) ( x - 3 )}

\frac{x - 1}{( x + 3 ) ( x - 3 )} < 0

Identify the intervals

x < - 3 or 1 < x < 3
