What is the diameter of the circle ?
2x^2+2y^2-20x-20y-22=0
write your answer in simplified, rationalized form.

The answer to your question is diameter =

Step-by-step explanation:

                             2x² + 2y² - 20x - 20y - 22 = 0

Solution

                           2x² - 20x      + 2y²  - 20y       = 22

                            2(x² - 10x       )   + 2(y² - 10y       )  = 22

Complete perfect square trinomials

                            2(x² - 10x + 5²)  + 2(y² - 10y + 5²) = 22 + 50 + 50

Factorize

                            2(x - 5)² + 2(y - 5)² = 122

                              (x - 5)²  +  (y - 5)² = 61

radius =

diameter = 2r

diameter = 2
