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

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

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

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

Multiply (5 + w) * (6 + 5w)
(5(6 + 5w) + w(6 + 5w)) = 0
((6 * 5 + 5w * 5) + w(6 + 5w)) = 0
((30 + 25w) + w(6 + 5w)) = 0
(30 + 25w + (6 * w + 5w * w)) = 0
(30 + 25w + (6w + 5w2)) = 0

Combine like terms: 25w + 6w = 31w
(30 + 31w + 5w2) = 0

Solving
30 + 31w + 5w2 = 0

Solving for variable 'w'.
