x^3+2x^2-x-2<0

Solution

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

Solution

x < - 2 or - 1 < x < 1

+1

Interval Notation

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

Solution steps

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

Factor

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

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

Identify the intervals

x < - 2 or - 1 < x < 1

Popular Examples

simplify (5^1)/(5^4)simplify

\frac{5 ^{1}}{5 ^{4}}

1/(2-x^2)>= (16x)/(x^2-2)+8x

\frac{1}{2 - x ^{2}} \geq \frac{16 x}{x ^{2} - 2} + 8 x

x^2+10x+42=-3x+2

x^{2} + 10 x + 42 = - 3 x + 2

simplify (-5-2i)/(-3+5i)simplify

\frac{- 5 - 2 i}{- 3 + 5 i}

1 = 7 x
