↪Actually welcome to the concept of the completing square ..
↪Basically during this method , we have to generate a term and have to add that on the both sides to get a whole sqaure ..
↪thus the 3rd term is given as
↪=》 ( 1/2 * coefficient term of the "x")^2
↪thus here in the above equation this term would be as
↪=》 ( 1/2 * 4)^2 = (2)^2 = 4
↪But the Carly has added the term 16 , which is totally wrong , thus the option D.) is correct
↪D.) She added the wrong value to both the sides of the equation to complete the square
