The nonreal solutions to the polynomial equation are: (2 + i√11, 2 - i√11).
How to determine the nonreal solutions?
By critically observing the graph given, we can logically deduce that the real solutions of the polynomial are -1 and 4. This ultimately implies that, the given polynomial expression can be evaluated as follows:
(x + 1)(x - 4) = x² - 3x - 4.
x⁴ - 7x³ + 23x² - 29x - 60 = x² - 3x - 4.
Also, the nonreal solutions can be determined by dividing the polynomial expression by the real solutions as follows:
Nonreal solutions = (x⁴ - 7x³ + 23x² - 29x - 60)/(x² - 3x - 4)
Nonreal solutions = (2 + i√11, 2 - i√11).
