Solution for (7+w)(2w-3)=0 equation:


Simplifying
(7 + w)(2w + -3) = 0

Reorder the terms:
(7 + w)(-3 + 2w) = 0

Multiply (7 + w) * (-3 + 2w)
(7(-3 + 2w) + w(-3 + 2w)) = 0
((-3 * 7 + 2w * 7) + w(-3 + 2w)) = 0
((-21 + 14w) + w(-3 + 2w)) = 0
(-21 + 14w + (-3 * w + 2w * w)) = 0
(-21 + 14w + (-3w + 2w2)) = 0

Combine like terms: 14w + -3w = 11w
(-21 + 11w + 2w2) = 0

Solving
-21 + 11w + 2w2 = 0
