Question

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

Answer 1

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

Answer 2

hw did u get 4 ?

the given polynomial i see, it has :
-9, multiplicity 2; 9 multiplicity 3

Answer 3

i ment 3

Answer 4

**3

Answer 5

ohhk got u, but 3 is not a zero

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

thats all :)

Answer 10

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

Answer 11

correct !

Answer 12

thanks alot !

Answer 13
