Question

multiple zeros and multiplicity help. check my answer.

Answer 1

f(x)=(x+4)(x-2)(x-4)(x+4) the multiple zero is 2 and the multiplicity is 4

Answer 2

no wait other way around lol

Answer 3

No. Look, can you please write down the zeros from the factors -
x+4 --> Zero is -4
x-2 --> Zero is 2
x-4 --> Zero is 4
x+4 --> Zero is -4

Answer 4

Ring any bells ?

Answer 5

yes lol

Answer 6

So can I hear the answer , I mean READ the answer lol :P

Answer 7

but 4 shows up the most and 2 goes into it

Answer 8

Actually -4 shows up the most and that too two times :)

So the multiple zero is -4 and the multiplicity is two. Multiplicity means the number of times a particular zero appears. Since -4 appears two times, its multiplicity is two :)

Likewise, if somebody ask me to tell the multiplicity of 2, I will say it is 1, bcoz 2 comes only once :)

All ok ?

Answer 9

Any problem in grasping anything ? :)
