Question 1183371
<font face="Times New Roman" size="+2">


My graphing utility shows a real zero at *[tex \Large x\ =\ 4]



Use either synthetic division to divide the coefficient list by 4 or polynomial long division to divide the given polynomial by *[tex \Large x\ -\ 4].  The quotient will be a quadratic that you can solve with either the quadratic formula or by completing the square to obtain the two complex zeros.
