Question

Which system of equations can be used to find the roots of the equation 12x3-5x=2x2+x+6

Answer 1

Same=same figure out what the x is both x are the same number on both side is the same answer hope that helps

Answer 2

`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

The solution is

`x=1.07`
