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

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

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

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

Multiply (7 + w) * (-6 + 5w)
(7(-6 + 5w) + w(-6 + 5w)) = 0
((-6 * 7 + 5w * 7) + w(-6 + 5w)) = 0
((-42 + 35w) + w(-6 + 5w)) = 0
(-42 + 35w + (-6 * w + 5w * w)) = 0
(-42 + 35w + (-6w + 5w2)) = 0

Combine like terms: 35w + -6w = 29w
(-42 + 29w + 5w2) = 0

Solving
-42 + 29w + 5w2 = 0

Solving for variable 'w'.
