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

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

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

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

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

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

Solving
-54 + 15w + 4w2 = 0

Solving for variable 'w'.
