Solution for (2w+7)(w-6)=0 equation:


Simplifying
(2w + 7)(w + -6) = 0

Reorder the terms:
(7 + 2w)(w + -6) = 0

Reorder the terms:
(7 + 2w)(-6 + w) = 0

Multiply (7 + 2w) * (-6 + w)
(7(-6 + w) + 2w * (-6 + w)) = 0
((-6 * 7 + w * 7) + 2w * (-6 + w)) = 0
((-42 + 7w) + 2w * (-6 + w)) = 0
(-42 + 7w + (-6 * 2w + w * 2w)) = 0
(-42 + 7w + (-12w + 2w2)) = 0

Combine like terms: 7w + -12w = -5w
(-42 + -5w + 2w2) = 0
