(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 = 17w
(-12 + 17w + 5w2) = 0

Solving
-12 + 17w + 5w2 = 0

Solving for variable 'w'.
