-2x^2(x-8)<0

Solution

- 2 x^{2} (x - 8) < 0

Solution

x > 8

+1

Interval Notation

(8, \infty)

Solution steps

- 2 x^{2} (x - 8) < 0

Rewrite in standard form

- x^{3} + 8 x^{2} < 0

Factor

- x^{3} + 8 x^{2} : - x^{2} (x - 8)

- x^{2} (x - 8) < 0

Multiply both sides by

- 1

(reverse the inequality)

(- x^{2} (x - 8)) (- 1) > 0 \cdot (- 1)

Simplify

x^{2} (x - 8) > 0

Identify the intervals

x > 8
