Gabriella is solving the equation x^2+2x-8=0x 2 +2xβ8=0 by completing the square with the steps below. Step 1: x^2+2x=-8x 2 +2x=β8 Step 2: x^2+2x+1=8+1x 2 +2x+1=8+1 Step 3: \left(x+1\right)^2=9(x+1) 2 =9 Step 4: x+1=\pm\sqrt{9}x+1=Β± 9 β Step 5: x=-1\pm\sqrt{9}x=β1Β± 9 β Gabriella finds out that her final answer is incorrect. During which step did Gabriella make her initial error, if using completing the square? Step 1 Step 2 Step 3 Step 4
