Best ResponseYou've already chosen the best response.1same way... 2x^2  2z^4 + y^2  x^2 + z^4....x = 4, y = 3, z = 2 sub 2(4^2)  2(2^4) + 3^2 (4^2) + 2^4.....you got to be very careful with your signs now, you take it from here....I will stay and check your work. If you have any questions at all, just ask. Take as long as you need.
