Subproblem 1
Set the factor '(2 + s)' equal to zero and attempt to solve:

Simplifying
2 + s = 0

Solving
2 + s = 0

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

Add '-2' to each side of the equation.
2 + -2 + s = 0 + -2

Combine like terms: 2 + -2 = 0
0 + s = 0 + -2
s = 0 + -2

Combine like terms: 0 + -2 = -2
s = -2

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

Simplifying
1 + 3s = 0

Solving
1 + 3s = 0

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

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

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

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

Divide each side by '3'.
s = -0.3333333333

Simplifying
s = -0.3333333333
Solution
s = {-2, -0.3333333333}
