m = -5, n = -3
m = 0, n = -3
m = -3, n = 0

Answer 1

Hint: Set the denominator equal to 0 and solve

m*n + 3*m = 0

m*(n + 3) = 0 ... factor out the GCF

the two solutions to the equation above are what?

Answer 2

the first one?

Answer 3

another hint:

if A*B = 0, then A = 0 or B = 0

Answer 4

oh so its the second one?
