Determine the center and radius of the following circle equation: x^2+y^2-14x+4y+52=0 x 2 +y 2 −14x+4y+52=0

Step-by-step explanation:

x² + y² - 14x + 4y + 52 = 0

(x - 7)² - 49 + (y + 2)² - 4 + 52 = 0

(x - 7)² + (y + 2)² = 1

Hence the circle's center is (7, -2) and the radius is 1.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
