square root x+16=2+square root x+4. I tried doing this problem and got 7/3. and i know that is really wrong. can anyone please show me the steps to doing this problem. thanks:)
square both sides x+16 = 4 + 4√(x+4) + x+4 8 = 4√(x+4) 2 = √(x+4) square again 4 = x+4 x = 0 test it in the original equation.
