To identify the multiplicities of the linear factors of the polynomial \( h(x) = (x+4)(x-1)^2(x+3)^5 \), we can analyze each factor in the expression:
- The factor \( (x + 4) \) has a multiplicity of 1 because it appears only once.
- The factor \( (x - 1)^2 \) has a multiplicity of 2 because it appears with an exponent of 2.
- The factor \( (x + 3)^5 \) has a multiplicity of 5 because it appears with an exponent of 5.
In summary, the multiplicities of the linear factors are:
- \( x + 4 \): multiplicity 1
- \( x - 1 \): multiplicity 2
- \( x + 3 \): multiplicity 5
