-3x^2>2x-1

Solution

- 3 x^{2} > 2 x - 1

Solution

- 1 < x < \frac{1}{3}

+2

Solution steps

- 3 x^{2} > 2 x - 1

Rewrite in standard form

- 3 x^{2} + 1 - 2 x > 0

Factor

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

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

Multiply both sides by

- 1

(reverse the inequality)

(- (3 x - 1) (x + 1)) (- 1) < 0 \cdot (- 1)

Simplify

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

Identify the intervals

- 1 < x < \frac{1}{3}
