(5w+3)(5+w)=0

Solution for (5w+3)(5+w)=0 equation:

Simplifying
(5w + 3)(5 + w) = 0

Reorder the terms:
(3 + 5w)(5 + w) = 0

Multiply (3 + 5w) * (5 + w)
(3(5 + w) + 5w * (5 + w)) = 0
((5 * 3 + w * 3) + 5w * (5 + w)) = 0
((15 + 3w) + 5w * (5 + w)) = 0
(15 + 3w + (5 * 5w + w * 5w)) = 0
(15 + 3w + (25w + 5w2)) = 0

Combine like terms: 3w + 25w = 28w
(15 + 28w + 5w2) = 0

Solving
15 + 28w + 5w2 = 0

Solving for variable 'w'.
