(6+w)(5w-7)=0

Solution for (6+w)(5w-7)=0 equation:

Simplifying
(6 + w)(5w + -7) = 0

Reorder the terms:
(6 + w)(-7 + 5w) = 0

Multiply (6 + w) * (-7 + 5w)
(6(-7 + 5w) + w(-7 + 5w)) = 0
((-7 * 6 + 5w * 6) + w(-7 + 5w)) = 0
((-42 + 30w) + w(-7 + 5w)) = 0
(-42 + 30w + (-7 * w + 5w * w)) = 0
(-42 + 30w + (-7w + 5w2)) = 0

Combine like terms: 30w + -7w = 23w
(-42 + 23w + 5w2) = 0

Solving
-42 + 23w + 5w2 = 0

Solving for variable 'w'.
