Determine the total number of roots of each polynomial function using the factored form. f (x) = (x + 2) (x - 1) [x - (4 + 3i) ][x - (4 - 3i) ]

There are always the same number of roots as there are powers of x. So in this case, there are 4 x's and therefore there are 4 roots of the polynomial.

It is important to note that there are only 2 real roots though. The last two roots in this equation are not real due to the number 'i' being included in both of them.
