Carly solved a quadratic equation by completing the square, but her work has errors.
a(i + 4) = 117
12 + 40 = 117
x2 + 40 + 42 = 117 + 42
12 + 40 + 16 = 117 + 16
(1 + 4) = 133
+ 4 = + v133
i= -4 = v133

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.
