    standard form is Ax + By = C. What you need to do first is distribute (x - 2)2, or to make it easier 2(x - 2), which distributed is 2x - 4.

    That would make 2x - 4 + 4, and when you add like terms you get simply 2x.

    Then you need to get it into standard form, which means you add -2x to both sides. That gives you -2x + y = 0

    and since A = positive integer, multiply everything in the equation by -1, making 2x - y = 0.

    That gives you your standard form.
