-x^2+3x-2<0

Solution

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

Solution

x < 1 or x > 2

+1

Interval Notation

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

Solution steps

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

Factor

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

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

Multiply both sides by

- 1

(reverse the inequality)

(- (x - 1) (x - 2)) (- 1) > 0 \cdot (- 1)

Simplify

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

Identify the intervals

x < 1 or x > 2
