y=-2%2A%28x-2%29%5E2
First you simplify, i.e. square the expression in the bracket.
y+=+-2%2A%28+%28x-2%29%2A%28x-2%29+%29

FOIL:
y+=+-2%2A%28x%2Ax+-+2%2Ax+-+2%2Ax+%2B+2%2A2%29
y+=+-2%2A%28x%5E2+-+4x+%2B+4%29

Now you expand the bracket (multiply everything with -2):
y+=+2x%5E2+%2B+8x+-+8

That's it. The standard form of a curve is y+=+Ax%5E2+%2B+Bx+%2B+C.
