(2w-5)(6+w)=0

Solution for (2w-5)(6+w)=0 equation:

Simplifying
(2w + -5)(6 + w) = 0

Reorder the terms:
(-5 + 2w)(6 + w) = 0

Multiply (-5 + 2w) * (6 + w)
(-5(6 + w) + 2w * (6 + w)) = 0
((6 * -5 + w * -5) + 2w * (6 + w)) = 0
((-30 + -5w) + 2w * (6 + w)) = 0
(-30 + -5w + (6 * 2w + w * 2w)) = 0
(-30 + -5w + (12w + 2w2)) = 0

Combine like terms: -5w + 12w = 7w
(-30 + 7w + 2w2) = 0

Solving
-30 + 7w + 2w2 = 0

Solving for variable 'w'.
