I need help solving this problem using the FOIL method. I need the answer asap. this is the expression I am trying to solve and simplify, 3+√z-1 = √z+14 the right side radical is already isolated so I squared both sides. (3+√z-1)^2 = (√z+14)^2. Now it is asking me to use FOIL to simplify the left side, and I do not know how. Can someone please help me?
