a quadratic only has two roots
You have two factors, so there are two roots, each of multiplicity 1.
If h is a root of multiplicity n, then (x-h)^n is a factor of the polynomial.
(x+4) = (x+4)^1 so -4 has multiplicity 1.
If you were stuck on this, you really need to study the section on your text, or google the topic for examples.
The quadratic equation x^2+2x−8=0 can be rewritten as (x+4)(x−2)=0.
What is the multiplicity of the root x=−4?
A.The multiplicity of the root is 1.
B.The multiplicity of the root is 3.
C.The multiplicity of the root is 2.
D.The multiplicity of the root is 4.
