(5w+7)(6+w)=0

Solution for (5w+7)(6+w)=0 equation:

Simplifying
(5w + 7)(6 + w) = 0

Reorder the terms:
(7 + 5w)(6 + w) = 0

Multiply (7 + 5w) * (6 + w)
(7(6 + w) + 5w * (6 + w)) = 0
((6 * 7 + w * 7) + 5w * (6 + w)) = 0
((42 + 7w) + 5w * (6 + w)) = 0
(42 + 7w + (6 * 5w + w * 5w)) = 0
(42 + 7w + (30w + 5w2)) = 0

Combine like terms: 7w + 30w = 37w
(42 + 37w + 5w2) = 0

Solving
42 + 37w + 5w2 = 0

Solving for variable 'w'.
