Suppose you know that 3 is one of the zeros of the polynomial p=x^3-x^2-11x+15.
Find all the other zeros.
Briefly explain why you know that you have found all of the zeros.
Hello, gumi!
Suppose you know that 3 is one of the zeros of:
Find all the other zeros.
Briefly explain why you know that you have found all of the zeros.
If is a zero of , then is a factor of
We find that: .
. . And the other two zeros of are: .
A cubic polynomial can have at most three zeros.
