Carly solved a quadratic equation by completing the square, but her work has errors.

identify the first error in carly's work.

a. she did not rewrite the equation and set it equal to 0 as a first step.
b. she put the ± symbol in the wrong place after taking the square root.
c. she should have subtracted the value from the right side of the equation instead of adding.
d. she added the wrong value to both sides of the equation to complete the square.

⭐Here IS YOUR Answer...!!!



↪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
