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

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

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

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

Multiply (6 + 5w) * (7 + w)
(6(7 + w) + 5w * (7 + w)) = 0
((7 * 6 + w * 6) + 5w * (7 + w)) = 0
((42 + 6w) + 5w * (7 + w)) = 0
(42 + 6w + (7 * 5w + w * 5w)) = 0
(42 + 6w + (35w + 5w2)) = 0

Combine like terms: 6w + 35w = 41w
(42 + 41w + 5w2) = 0

Solving
42 + 41w + 5w2 = 0

Solving for variable 'w'.
