SOLUTION: Good evening One more question. I think I have the answer yet i'm only 60% sure. Find all the zeros of f(x) if f(x) =(x^2-4)^3. Identify any multiple zeros. f(x)=0 (x^2-4

Question 257025: Good evening
One more question. I think I have the answer yet i'm only 60% sure.
Find all the zeros of f(x) if f(x) =(x^2-4)^3. Identify any multiple zeros.
f(x)=0
(x^2-4)^3=0
F(4)=(4^2-4)^3=48-12=36-36=0
F(0)=(0^2-4)^3=0-12=-12+12=0
Answer: {4, (triple zero)}
Thank you much

The original question was
f(x) =(x^2-4)^3.
step 1 - set = 0 to get
(i)
take a cube root to get
(ii)
Factoring, we get
(iii)
x = 2 and x = -2
It turns out that
x = 2 with multiplicity 3
x = -2 with multiplicity 3
