Subproblem 1
Set the factor '(15 + m)' equal to zero and attempt to solve:

Simplifying
15 + m = 0

Solving
15 + m = 0

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

Add '-15' to each side of the equation.
15 + -15 + m = 0 + -15

Combine like terms: 15 + -15 = 0
0 + m = 0 + -15
m = 0 + -15

Combine like terms: 0 + -15 = -15
m = -15

Simplifying
m = -15
Subproblem 2
Set the factor '(1 + m)' equal to zero and attempt to solve:

Simplifying
1 + m = 0

Solving
1 + m = 0

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

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

Combine like terms: 1 + -1 = 0
0 + m = 0 + -1
m = 0 + -1

Combine like terms: 0 + -1 = -1
m = -1

Simplifying
m = -1
Solution
m = {-15, -1}
