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

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

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

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

Multiply (5 + 4w) * (6 + w)
(5(6 + w) + 4w * (6 + w)) = 0
((6 * 5 + w * 5) + 4w * (6 + w)) = 0
((30 + 5w) + 4w * (6 + w)) = 0
(30 + 5w + (6 * 4w + w * 4w)) = 0
(30 + 5w + (24w + 4w2)) = 0

Combine like terms: 5w + 24w = 29w
(30 + 29w + 4w2) = 0

Solving
30 + 29w + 4w2 = 0

Solving for variable 'w'.
