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

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

Simplifying
(3w + 7)(6 + -1w) = 0

Reorder the terms:
(7 + 3w)(6 + -1w) = 0

Multiply (7 + 3w) * (6 + -1w)
(7(6 + -1w) + 3w * (6 + -1w)) = 0
((6 * 7 + -1w * 7) + 3w * (6 + -1w)) = 0
((42 + -7w) + 3w * (6 + -1w)) = 0
(42 + -7w + (6 * 3w + -1w * 3w)) = 0
(42 + -7w + (18w + -3w2)) = 0

Combine like terms: -7w + 18w = 11w
(42 + 11w + -3w2) = 0

Solving
42 + 11w + -3w2 = 0

Solving for variable 'w'.
