Find the zeros of the polynomial function and state the multiplicity of each.
f(x) = 3(x + 9)^2(x - 9)^3

Question

Find the zeros of the polynomial function and state the multiplicity of each. 
f(x) = 3(x + 9)^2(x - 9)^3

anonymous · Answer

4, multiplicity 1; 9, multiplicity 1; -9, multiplicity 1
correct?

ganeshie8 · Answer

hw did u get 4  ? 

the given polynomial i see, it has  : 
-9, multiplicity 2; 9 multiplicity 3

anonymous · Answer

i ment 3

anonymous · Answer

**3

ganeshie8 · Answer

ohhk got u, but 3 is not a zero

ganeshie8 · Answer

for 3 to be a zero of polynomial, we should have (x-3) as factor.

anonymous · Answer

oh i see im going to get see if i get the same thing as u

ganeshie8 · Answer

ok :) but this is a q, we can answer just by looking at the polynomial.

1) i see, (x+9)^2 as a factor, so -9 is a zero, with multiplicity of 2

ganeshie8 · Answer

2) i see, (x-9)^3 as a factor, so 9 is a zero, with multiplicity of 3

thats all :)

anonymous · Answer

-9, multiplicity 2; 9, multiplicity 3 right ???

ganeshie8 · Answer

correct !
