Carlos graphed the system of equations that can be used to solve x cubed minus 2 x squared + 5 x minus 6 = negative 4 x squared + 14 x + 12. On a coordinate plane, 2 functions are shown. The functions intersect at (negative 3, negative 66), (negative 2, negative 32), and (3, 18)

What are the roots of the polynomial equation?
–3, –2, 3
–3, 2
18, 32
18, 32, 66
