Question

Find the zeros of the polynomial function and state the multiplicity of each.
f(x)=4(x+9)^2(x-9)^3

Answer 1

-9 multiplicity 2
9 multiplicity 3

Answer 2

how do you figure out the multiplicity though?

Answer 3

the exponents

Answer 4

THINK: if you have y=(x+9)^2, how many roots does it have?
the polynomial is degree 2 so it has two roots
-9 and -9

Answer 5

thanks. that makes sense

Answer 6

np :)
