Simplifying
(1 + w)(4w + -7) = 0

Reorder the terms:
(1 + w)(-7 + 4w) = 0

Multiply (1 + w) * (-7 + 4w)
(1(-7 + 4w) + w(-7 + 4w)) = 0
((-7 * 1 + 4w * 1) + w(-7 + 4w)) = 0
((-7 + 4w) + w(-7 + 4w)) = 0
(-7 + 4w + (-7 * w + 4w * w)) = 0
(-7 + 4w + (-7w + 4w2)) = 0

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

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

Solving for variable 'w'.
