(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).

Explanation:
→ 2(3x + 9x) - 6x(4x - 8x) = 0
→ 6x + 18x - 24x² + 48x² = 0
→ 24x + 24x² = 0
Rearrange terms :
→ 24x² + 24x = 0
Common factor :
→ 24(x² + x) = 0
Divide both sides of the equation by the same term :
→ 24(x² + x) = 0
→ x² + x = 0
SOLUTION :
x = 0
x = -1
