Question

Find all the real zeros of the polynomial function:
f(x)=x^2+10x+25 and determine the multiplicity of each zero.

Answer 1

I factored and got (x+5)(x+5) which gave me x=-5. so would -5 be the real zero? what is multiplicity and how do i find it?

Answer 2

the multiplicity is equal to the exponential of your largest term

Answer 3

so multiplicity is 2?

Answer 4

it says to find all real zeros so would it just be -5 or would it be +/- 5?

Answer 5

that helps! thanks :)

Answer 6

multiplicity is means you have a *repeated* root.

notice that you got x= - 5 twice. the multiplicity is 2

ehuman has made a rare mistake here.

Answer 7

no it is just negative 5, multiplicity of 2

Answer 8

thanks so much to both of you! :)

Answer 9

oh snap, multiplicity.... i need coffee

Answer 10

haha believe me it is way too early for me to function let alone learn pre-cal :p

Answer 11

im going to stop until I get daid coffee. ☺

Answer 12

haha no problem,, thanks again! :)
