(3w-7)(1+w)=0

Solution for (3w-7)(1+w)=0 equation:

Simplifying
(3w + -7)(1 + w) = 0

Reorder the terms:
(-7 + 3w)(1 + w) = 0

Multiply (-7 + 3w) * (1 + w)
(-7(1 + w) + 3w * (1 + w)) = 0
((1 * -7 + w * -7) + 3w * (1 + w)) = 0
((-7 + -7w) + 3w * (1 + w)) = 0
(-7 + -7w + (1 * 3w + w * 3w)) = 0
(-7 + -7w + (3w + 3w2)) = 0

Combine like terms: -7w + 3w = -4w
(-7 + -4w + 3w2) = 0

Solving
-7 + -4w + 3w2 = 0

Solving for variable 'w'.
