-5X(-3X-1)>2(-X+1)

- 5 X (- 3 X - 1) > 2 (- X + 1)

X < - \frac{2}{3} or X > \frac{1}{5}

Interval Notation

(- \infty, - \frac{2}{3}) \cup (\frac{1}{5}, \infty)

Decimal Notation

X < - 0.66666 \dots or X > 0.2

Solution steps

- 5 X (- 3 X - 1) > 2 (- X + 1)

Rewrite in standard form

15 X^{2} + 7 X - 2 > 0

Factor

15 X^{2} + 7 X - 2 : (5 X - 1) (3 X + 2)

(5 X - 1) (3 X + 2) > 0

Identify the intervals

X < - \frac{2}{3} or X > \frac{1}{5}

30 < 2 x - 6

0.25 \cdot 6

\frac{3 c - 2}{8 c} - \frac{5 c - 2}{6 c}

\frac{5}{3} x + (2 x + 1) (\frac{1}{3} x - 1) = 0

6 (x - 3) = 3 x + 9
