A square in the coordinate plane is shown below, with its vertices at A(1, 0), B(1, 1), C(0, 1), and D(0, 0). Since the squared distance between points P(x, y) and Q(a, b) is given by the formula PQ² = (x – a)2 + (y – b)2, we see that PA? = (x- 1)2 + (y- 0)2 = x2 – 2x +1+y² is the squared distance between P and vertex A of the square. Complete parts (a) and (b) below. (a) Find PB?, PC², and PD². Type answers in expanded form.
