Think of "multiplicity" as "exponents of the roots". So now "roots" have to do with x values. We need roots where x = 0, -1 means that "x+1=0", because when x=-1, -1+1=0, that statement is true. Since that "x+1" has a multiplicity of 2, we'll square that value:
The single root of 3 can be written as "x-3=0", because plugging in 3 for x makes that statement true: 3-3=0
Now we combine the terms by multiplying them and set that equal to 0:
