Answer 2

\[\left( a-b \right)^2=a^2+b^2-2ab\]

Answer 3

wut??

Answer 4

(x - 2)^2 + y^2 = 64

Subtract (x - 2)^2 from both sides of the equation.

(x - 2)^2 + y^2 = 64

- (x - 2)^2 -(x - 2)^2
------------------------------

Answer 5

y^2 = 64 - (x - 2)^2

What does this equal when you simplify?

--> 64 - (x - 2)^2 =
