well there are 2 imaginary roots, if you are given 4 + i the conjugate is also a root 4 - i these roots come in pairs sometimes written \[x = 4 \pm i\] you are told 2 roots are real, -2, 2 a degree 5 polynomial has 5 roots.... so since imaginary roots come in pairs, the 5th root has to be real... hope that helps
So three real roots and two imaginary? Or would the all be considered "real"
your choice of 3 real 2 imaginary is the answer
