Best ResponseYou've already chosen the best response.0Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credit. \[x ^{2} + 2x + y ^{2} + 4y = 20\]

Best ResponseYou've already chosen the best response.0This is what I have so far x² + 2x + y² + 4y = 20 (x² + 2x) + (y² + 4y) = 20 (x² + 2x+1) + (y² + 4y+4) = 20 + (1 + 4) (x² + 2x+1) + (y² + 4y+4) = 25

Best ResponseYou've already chosen the best response.0I have been using this for the steps. I'm on step 4, but I can't quite seem to figure out how to "factor each quadratic".

Best ResponseYou've already chosen the best response.0\[x ^{2} + 2x + y ^{2} + 4y = 20\] half of 2 is 1, \(6^2=1\) half of 4 is 2, \(2^2=4\) go right from there to \[(x+1)^2+(y+2)^2=20+1+4\]
