How do i do this?

3= 6x^2 - 2x -8

What are you doing with it?

Are you trying to solve for x?

If so, you have to subtract 3 from both sides so one side = 0

0 = 6x^2 -2x - 11

If this won't factor, you can use the quadratic equation to solve for x.

-b +/- (the square root of (b^2-4ac))

all of this divided be 2a.
