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

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

Simplifying
(5w + 7)(6 + -1w) = 0

Reorder the terms:
(7 + 5w)(6 + -1w) = 0

Multiply (7 + 5w) * (6 + -1w)
(7(6 + -1w) + 5w * (6 + -1w)) = 0
((6 * 7 + -1w * 7) + 5w * (6 + -1w)) = 0
((42 + -7w) + 5w * (6 + -1w)) = 0
(42 + -7w + (6 * 5w + -1w * 5w)) = 0
(42 + -7w + (30w + -5w2)) = 0

Combine like terms: -7w + 30w = 23w
(42 + 23w + -5w2) = 0

Solving
42 + 23w + -5w2 = 0

Solving for variable 'w'.
