(6+w)(4w+7)=0

Solution for (6+w)(4w+7)=0 equation:

Simplifying
(6 + w)(4w + 7) = 0

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

Multiply (6 + w) * (7 + 4w)
(6(7 + 4w) + w(7 + 4w)) = 0
((7 * 6 + 4w * 6) + w(7 + 4w)) = 0
((42 + 24w) + w(7 + 4w)) = 0
(42 + 24w + (7 * w + 4w * w)) = 0
(42 + 24w + (7w + 4w2)) = 0

Combine like terms: 24w + 7w = 31w
(42 + 31w + 4w2) = 0

Solving
42 + 31w + 4w2 = 0

Solving for variable 'w'.
