The Richter scale is used to measure the intensity of an earthquake. If E, measured in joules, is the energy released during an
earthquake, then the magnitude is given by where joules.
If joules of energy are released during an earthquake, what is the magnitude of the earthquake?

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?
