+1

Interval Notation

(- \infty, - 5) \cup (4, \infty)

Solution steps

(x - 4) (x + 5) > 0

Identify the intervals

x < - 5 or x > 4

Popular Examples

\frac{1}{( 2 x + 1 )} > 0

2 x^{2} - 2 x + 3 > 0

((2-3x))/((3-2x))>= 0

\frac{( 2 - 3 x )}{( 3 - 2 x )} \geq 0

((x+4))/((x^2+4x+4))>((x-2))/((x^2-4))

\frac{( x + 4 )}{( x ^{2} + 4 x + 4 )} > \frac{( x - 2 )}{( x ^{2} - 4 )}

(a^2)/((a^4+1))>= 1/2

\frac{a ^{2}}{( a ^{4} + 1 )} \geq \frac{1}{2}
