Question

Write in standard form: x² - 10x + y² - 4y = -28

Answer 1

(x - 5) ^2 + (y -2)^2 = 1

Explanation:

This is for a circle.

We need to complete the square

(x^2 -10x ) + ( y^2 -4y ) = -28

(x^2 - 10x +25) + (y^2 - 4y 2y) = -28 + 25 + 4

(x-5)^2 + (y-2)^2 = 1

The center of this circle would be (5,2) with a radius of 1.
