 Question 618271: What is the solution of the square root of two x plus four (square root bracket thing over two x plus four) equals x minus two?Answer by unlockmath(1614)   (Show Source): You can put this solution on YOUR website!Hello, Let's write this out as: sq rt(2x+4)=x-2 Square both sides: 2x+4=(x-2)^2 Expand this out: 2x+4=x^2-4x+4 Subtract 2x and 4: 0=x^2-6x Factor: x(x-6) Solve for x: x=0 x=6 check each answer to see if they work: 0 doesn't work 6 does. Make sense? RJ www.math-unlock.com
