Answer:
f(x) =
Step-by-step explanation:
First of all, if 2 - i is a zero, then so is 2 + i
All you need to do now is multiply (x - 1)(x - 3)(x - 2 + i)(x - 2 - i)
I will do part of that multiplication
(x - 2 + i)(x - 2 - i) = - 2x - xi - 2x + 4 + 2i + xi - 2i -
= - 4x + 5
So, now (x - 1)(x - 3)( - 4x + 5) =
I will let you finish that multiplication. I did some and you can do some. OK?
Square roots that are not perfect squares are irrational.
An example could be √0.5 which equals 0.7071067811...
