HELP ASAP PLEASE After factoring the following polynomial completely, use the Fundamental Theorem of Algebra to determine the number of roots of the polynomial. Then, determine which of the factors has a multiplicity of 3.

(x + 7)(x – 2)^2(x^2 – 4)(x + 1)^4
Number of roots:
Factor with multiplicity of 3:
