Question 1093402: Find the possible rational zeros, and then find all the zeros of the polynomial function:
f(x)=x^3-63x+162
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
f(x) = x^3 -63x +162
:
this polynomial function can be factored
:
(x-6) * (x-3) * (x+9) = x^3 -63x +162
:
zeros are x=6, x=3, x=-9
:
these are all the zeros over the real numbers
