(5w+6)(4+w)=0

Solution for (5w+6)(4+w)=0 equation:

Simplifying
(5w + 6)(4 + w) = 0

Reorder the terms:
(6 + 5w)(4 + w) = 0

Multiply (6 + 5w) * (4 + w)
(6(4 + w) + 5w * (4 + w)) = 0
((4 * 6 + w * 6) + 5w * (4 + w)) = 0
((24 + 6w) + 5w * (4 + w)) = 0
(24 + 6w + (4 * 5w + w * 5w)) = 0
(24 + 6w + (20w + 5w2)) = 0

Combine like terms: 6w + 20w = 26w
(24 + 26w + 5w2) = 0

Solving
24 + 26w + 5w2 = 0

Solving for variable 'w'.
