x^3+x^2-4x-4>0

Solution

x^{3} + x^{2} - 4 x - 4 > 0

Solution

- 2 < x < - 1 or x > 2

+1

Interval Notation

(- 2, - 1) \cup (2, \infty)

Solution steps

x^{3} + x^{2} - 4 x - 4 > 0

Factor

x^{3} + x^{2} - 4 x - 4 : (x + 1) (x + 2) (x - 2)

(x + 1) (x + 2) (x - 2) > 0

Identify the intervals

- 2 < x < - 1 or x > 2

Popular Examples

(x+6)^2-(x-6)^2<= 3x

(x + 6)^{2} - (x - 6)^{2} \leq 3 x

1/((x+1)-1)>= (2-1)/((x-2))

\frac{1}{( x + 1 ) - 1} \geq \frac{2 - 1}{( x - 2 )}

4(m+2)^2+4(m+2)(3m-1)<= 0

4 (m + 2)^{2} + 4 (m + 2) (3 m - 1) \leq 0

x^3+3x^2+5x+3>= 0

x^{3} + 3 x^{2} + 5 x + 3 \geq 0

((36x-7))/((2+3x))>= 12

\frac{( 36 x - 7 )}{( 2 + 3 x )} \geq 12
