Using PEMDAS, we know to multiply the two with the inside of the braket. That would give you (2x-8)=36. Then, you would have to add 8 on both side to cancel out the -8 which would leave you with 2x=44. Then you will divide each side by two to get the answer which is x=22
This isn't a quadratic equation. I'm assuming that you meant to put (x-4)2x=36
2x^2-8x-36=0

I would use the quadratic formula to solve it.

Best of luck!
