(2x^2)/3-x<(8x)/3 (1+x)+1

\frac{2 x ^{2}}{3} - x < \frac{8 x}{3} (1 + x) + 1

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

Interval Notation

(- \infty, - \frac{3}{2}) \cup (- \frac{1}{3}, \infty)

Decimal Notation

x < - 1.5 or x > - 0.33333 \dots

Solution steps

\frac{2 x ^{2}}{3} - x < \frac{8 x}{3} (1 + x) + 1

Rewrite in standard form

- 6 x^{2} - 11 x - 3 < 0

Factor

- 6 x^{2} - 11 x - 3 : - (3 x + 1) (2 x + 3)

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

Multiply both sides by

- 1

(reverse the inequality)

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

Simplify

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

Identify the intervals

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

3 r - 6 = 18
