Consider a student's steps to solve the radical equation X + 2 - x = 0, as shown here: √x+ 2 - x=0 >Vx+ 2 = x x + 2 = x2 x²-x-2=0 =(x-2)(x+1) = 0 x = 2, -1 are the solutions of the given radical equation. Show that one of the values does not satisfy the original radical equation. Use the logic of equation-solving to explain what went wrong in the process. Explain how the extra solution arose.
