Question

Is there a quick way to find the rational zeroes of a polynomial function?

Answer 1

List the possible rational roots and use synthetic division.

Answer 2

So use synthetic division for ALL of the possible roots? If i had say, 12 possible ones, i have to synthetically divide every single one of them?

Answer 3

Possibly not. You might find a root and then be able to factor the quotient.

Answer 4

Can you explain that?

Answer 5

If the remainder of the synthetic division process is 0, then you have found a factor. The other factor is the quotient of the synthetic division process.

Answer 6

Ok, i see what you mean. Thanks!
