Question

What is the result of isolating y^2 in the equation below (x+6)^2+y^2=1​

Answer 1

(x+6)^2 + y^2 = 1 then isolate y^2 by subtracting (x +6)^2 from both sides, we get

y^2 = 1 - (x + 6)^2

expanding the right side, we now have

y^2 = 1-(x^2 + 12x +36)

y^2 = 1-x^2-12x -36

y^2 = -x^2 -12x - 35 therefore the solution is choice A
