Use the function below to answer the question. f(x)=x^3+7x^2+16x+12=(x+2)(x+2)(x+3) What is the multiplicity of the root -3 ?

Question

Use the function below to answer the question.


`f(x)=x^3+7x^2+16x+12=(x+2)(x+2)(x+3)`

What is the multiplicity of the root -3 ?

Answer 1

1

Explanation:

(x +3) appears only once as a factor, hence the multiplicity of the root x=-3 is 1.
