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

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

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

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

Multiply (-4 + 5w) * (3 + w)
(-4(3 + w) + 5w * (3 + w)) = 0
((3 * -4 + w * -4) + 5w * (3 + w)) = 0
((-12 + -4w) + 5w * (3 + w)) = 0
(-12 + -4w + (3 * 5w + w * 5w)) = 0
(-12 + -4w + (15w + 5w2)) = 0

Combine like terms: -4w + 15w = 11w
(-12 + 11w + 5w2) = 0

Solving
-12 + 11w + 5w2 = 0

Solving for variable 'w'.
