(6+w)(4w-9)=0

Solution for (6+w)(4w-9)=0 equation:

Simplifying
(6 + w)(4w + -9) = 0

Reorder the terms:
(6 + w)(-9 + 4w) = 0

Multiply (6 + w) * (-9 + 4w)
(6(-9 + 4w) + w(-9 + 4w)) = 0
((-9 * 6 + 4w * 6) + w(-9 + 4w)) = 0
((-54 + 24w) + w(-9 + 4w)) = 0
(-54 + 24w + (-9 * w + 4w * w)) = 0
(-54 + 24w + (-9w + 4w2)) = 0

Combine like terms: 24w + -9w = 15w
(-54 + 15w + 4w2) = 0

Solving
-54 + 15w + 4w2 = 0

Solving for variable 'w'.
