x+1<6x^2

Solution

x + 1 < 6 x^{2}

Solution

x < - \frac{1}{3} or x > \frac{1}{2}

+2

Solution steps

x + 1 < 6 x^{2}

Rewrite in standard form

x + 1 - 6 x^{2} < 0

Factor

x + 1 - 6 x^{2} : - (3 x + 1) (2 x - 1)

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

Multiply both sides by

- 1

(reverse the inequality)

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

Simplify

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

Identify the intervals

x < - \frac{1}{3} or x > \frac{1}{2}
