Partially factored form: f(x) = (x − 3)(x + 3)(x2− 4x + 5) use the quadratic formula to identify the zeroes of x2 − 4x + 5. x =

The quadratic formula tells you that the solutions to

are given by

Filling in a=1, b=-4, c=5, this becomes

The zeros are 2+i andd 2-i.

i hope this is what you were looking for.
