(x-4)^2-28=8 I already got the answer but I will post it anyway because I dont know how to exit out of this screen

Hi there!

The correct answer is 10, -2.

Step-by-step explanation:

you first add 28 on both sides to get: (x-4)^2 = 36

then you square root both sides to get: x-4 = (+/-) 6

then you add four on both sides to get: x = 10, -2

step-by-step explanation:

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

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

853.3
