What does the sum of the multiplicities add up to

To answer this question, I'll make use of the following polynomial.

p(x) = x^3 - 7x^2 + 15x - 9

When factorized, the polynomial is:

p(x) = (x - 1)(x - 3)(x-3)

p(x) = (x - 1)(x - 3)^2

x-1 can be expressed as (x - 1)^1

So, we have:

p(x) = (x - 1)^1(x - 3)^2

The sum of multiplicity (M) of the equation is 3.

This is so because

x - 1 occurred one time in p(x) = (x - 1)(x - 3)^2

x - 3 occurred two times in p(x) = (x - 1)(x - 3)^2

Sum= 1 + 2

Sum= 3

The degree of p(x) = x^3 - 7x^2 + 15x - 9 or p(x) = (x - 1)^1(x - 3)^2 is 3.

This implies that:

Sum = Degree = 3

Hence: Option (a) answers the question
