Question

Express y = (x – 2)2 + 4 in standard form.

Answer 1

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.

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

That gives you your standard form.
