find the zeroes and state the multiplicity of multiple zeroes

Question

y=(x+1)^2 (x-1) (x-2)
I know that
x=-1
x=1
x=2
I don't know how to find the multiplicities

Answer 1

technicality here

from (x+1)^2
we have (x+1)(x+1)

so x = -1 or x = -1

same root shows up twice, so they call it a multiplicity of 2

your zeros are correct
