Susu is solving the quadratic equation 4x2 – 8x – 13 = 0 by completing the square. Her first four steps are shown in the table. In which step did Susu first make an error? Step 1 Step 2 Step 3 Step 4

Answer:Step 3 Step-by-step explanation:when solving by completing the square you are supposed to do (b/2)^2 and then add that to both sides.In your example (-8/2)^2=16 You are supposed to add sixteen to both sides not 64Susu forgot to divide 8 by 2 before she raised it to the to the second powerm that is why she got 64, which is incorrect.
