(3w+7)(w+6)=0

Solution for (3w+7)(w+6)=0 equation:

Simplifying
(3w + 7)(w + 6) = 0

Reorder the terms:
(7 + 3w)(w + 6) = 0

Reorder the terms:
(7 + 3w)(6 + w) = 0

Multiply (7 + 3w) * (6 + w)
(7(6 + w) + 3w * (6 + w)) = 0
((6 * 7 + w * 7) + 3w * (6 + w)) = 0
((42 + 7w) + 3w * (6 + w)) = 0
(42 + 7w + (6 * 3w + w * 3w)) = 0
(42 + 7w + (18w + 3w2)) = 0

Combine like terms: 7w + 18w = 25w
(42 + 25w + 3w2) = 0

Solving
42 + 25w + 3w2 = 0
