(5w+9)(6+w)=0

Solution for (5w+9)(6+w)=0 equation:

Simplifying
(5w + 9)(6 + w) = 0

Reorder the terms:
(9 + 5w)(6 + w) = 0

Multiply (9 + 5w) * (6 + w)
(9(6 + w) + 5w * (6 + w)) = 0
((6 * 9 + w * 9) + 5w * (6 + w)) = 0
((54 + 9w) + 5w * (6 + w)) = 0
(54 + 9w + (6 * 5w + w * 5w)) = 0
(54 + 9w + (30w + 5w2)) = 0

Combine like terms: 9w + 30w = 39w
(54 + 39w + 5w2) = 0

Solving
