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

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

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

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

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

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

Combine like terms: 7w + -6w = 1w
(-42 + 1w + w2) = 0

Solving
-42 + 1w + w2 = 0

Solving for variable 'w'.

-1w = 7

Divide each side by '-1'.
w = -7

Simplifying
w = -7
Subproblem 2
Set the factor '(6 + -1w)' equal to zero and attempt to solve:

Simplifying
6 + -1w = 0

Solving
6 + -1w = 0

Move all terms containing w to the left, all other terms to the right.

Add '-6' to each side of the equation.
6 + -6 + -1w = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1w = 0 + -6
-1w = 0 + -6

Combine like terms: 0 + -6 = -6
-1w = -6

Divide each side by '-1'.
w = 6

Simplifying
w = 6
Solution
w = {-7, 6}
