    the multiplicity is just the exponent. You don't actually have to solve it because you can just look at the equation and pick the answer, but if you were to solve it you'd separate them and have (x + 8)² = 0 (x + 8)(x + 8) = 0 x = -8 So -8 has a multiplicity of 2 because the exponent is 2. Same thing for 8. That has a multiplicity of 3 because the exponent on (x - 8) is 3
