Erica was using the COMPLETING THE SQUARE method to solve the quadratic equation below. 2x-12x-5=0 2x-12 +5 +5 5 2-12x+36 = 5 +36 41 Her friend Ryan, noticed that Jessica made an error or two and told her where she made her first mistake. Which of the below could be the error that Ryan told Jessica about? Erica should have subtracted 5 from both sides first. On the step where Erica added 36 to both sides, she really should have subtracted 36 from both sides. Just before Erica completed the square, she should have first divide both sides of the entire equation by 2. Erica should have added 6 to both sides before taking the square root of both sides.
