Math Problem Statement
Arlana graphed the system of equations that can be used to solve x cubed minus 5 x squared + 2 = negative x cubed + 17 x.
On a coordinate plane, 2 functions are shown. They intersect at (negative 2, negative 26), (0.11, 1.94), and (4.39, negative 9.81).
What are the roots of the polynomial equation? Round noninteger roots to the nearest hundredth. –26, –9.81, 1.94 –26 –2 –2, 0.11, 4.39
