2+5i is complex, and MUST be accompanied by its conjugate, 2-5i.
Thus, the factors of this 4th degree poly are (x-4)(x+8)(x-2-5i)(x-2+5i).
Multiply this out to obtain the poly in question. Then arrange the powers of x in descending order, beginning with x^4.
The slope will point downwards towards the left as the coefficient of x is negative and it the negative applies to the numerator
