A student evaluates x2 - 2y when x = 6 and y = 3 and gets the answer 0. If the answer is not correct, which is the most plausible error that would lead to the answer that the student obtained?
The student incorrectly calculated x in the following manner: x² = 62 = 36.
The student accidentally swapped the variables. Instead of calcuating x– 2y, he or she calculated y? - 2x
There is no error. The student's answer is correct.
The student failed to square the x part. This led to calculating r as 6 instead of 36.
