Subproblem 1
Set the factor '(-14 + -1w)' equal to zero and attempt to solve:

Simplifying
-14 + -1w = 0

Solving
-14 + -1w = 0

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

Add '14' to each side of the equation.
-14 + 14 + -1w = 0 + 14

Combine like terms: -14 + 14 = 0
0 + -1w = 0 + 14
-1w = 0 + 14

Combine like terms: 0 + 14 = 14
-1w = 14

Divide each side by '-1'.
w = -14

Simplifying
w = -14
Subproblem 2
Set the factor '(3 + -1w)' equal to zero and attempt to solve:

Simplifying
3 + -1w = 0

Solving
3 + -1w = 0

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

Add '-3' to each side of the equation.
3 + -3 + -1w = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1w = 0 + -3
-1w = 0 + -3

Combine like terms: 0 + -3 = -3
-1w = -3

Divide each side by '-1'.
w = 3

Simplifying
w = 3
Solution
w = {-14, 3}
