y=12x^{3}-5x -----> equation A

y=2x^{2} +x+6 ------> equation B

we have

12x^{3}-5x=2x^{2} +x+6

This equation can be rewritten in the following system of equations

y=12x^{3}-5x -----> equation A

y=2x^{2} +x+6 ------> equation B

we know that

The solution of the system of equations is the intersection point both graphs

using a graphing tool

see the attached figure
