Suppose that a classmate asked you why (2x+1)2 is not (4x2+1). Write down your response to the student.

    Did you mistake the placement of the 2 outside the parentheses in (2x+1)2 ?

    If not, I assuming this is to test your knowledge of mathematics

    Well, (2x + 1)2 is saying 2 times (2x + 1) which is 4x + 2

    \[(2x + 1)^{2}\neq 4x ^{2}+1\]

    In order for it to be 4x^2, it would have to multiply the 2x by 2x, which is not the case

    Basically, you would say the classmate multiplied incorrectly.

    It would help if you used the "Equation" button.

    The poster, is using (2x +1)2 instead of (2x + 1)^2

    If the poster used the "Equation" feature it would be clear.
