Group 3 Question 8

1 comment:

  1. The working is very clear.

    Area for improvement (Presentation)
    (c)(ii) Since you found answer as N x 4, it should be simplified to give 4N

    On another note, the final answer N^2 - 2N + 1 is correct.
    Can you find another way to express this answer?

    Total: 5 points - presentation = 4 points
