(5w-6)(5+w)=0

Solution for (5w-6)(5+w)=0 equation:

Simplifying
(5w + -6)(5 + w) = 0

Reorder the terms:
(-6 + 5w)(5 + w) = 0

Multiply (-6 + 5w) * (5 + w)
(-6(5 + w) + 5w * (5 + w)) = 0
((5 * -6 + w * -6) + 5w * (5 + w)) = 0
((-30 + -6w) + 5w * (5 + w)) = 0
(-30 + -6w + (5 * 5w + w * 5w)) = 0
(-30 + -6w + (25w + 5w2)) = 0

Combine like terms: -6w + 25w = 19w
(-30 + 19w + 5w2) = 0

Solving
-30 + 19w + 5w2 = 0

Solving for variable 'w'.
