Find the zeros of the polynomial function, and state the multiplicity of each.
The zeros are
(Use a comma to separate answers.)
The smaller zero has multiplicity
Therefore, the final answer is
Step 1 :Set the function
Step 2 :This equation will be true if either
Step 3 :Solving for x in each case:
Step 4 :For
Step 5 :For
Step 6 :Therefore, the zeros of the function are
Step 7 :The multiplicity of a zero is the number of times it appears as a root, which is given by the exponent of the factor in the polynomial
Step 8 :In this case, the factor
Step 9 :The factor
Step 10 :So, the zero -5 has a multiplicity of 4 and the zero 4 has a multiplicity of 1
Step 11 :Therefore, the final answer is
