Answer:
A.
Step-by-step explanation:
1) according to the given graph, the real roots are: -1 and 4, it means the given expression can be evaluated using (x+1)(x-4)=x²-3x-4.
2) if to divide the given expression by (x²-3x-4), then
x⁴-7x³+23x²-29x-60=(x²-3x-4)(x²-4x-15), where
3) x=-1;4 - real roots, and
[tex]x=2^+_-i\sqrt{11} \ -nonreal \ roots.[/tex]
