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

Solution for (4+w)(5w+3)=0 equation:

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

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

Multiply (4 + w) * (3 + 5w)
(4(3 + 5w) + w(3 + 5w)) = 0
((3 * 4 + 5w * 4) + w(3 + 5w)) = 0
((12 + 20w) + w(3 + 5w)) = 0
(12 + 20w + (3 * w + 5w * w)) = 0
(12 + 20w + (3w + 5w2)) = 0

Combine like terms: 20w + 3w = 23w
(12 + 23w + 5w2) = 0

Solving
12 + 23w + 5w2 = 0

Solving for variable 'w'.
