Complete the square and write the equation in standard form. Then give the center and radius of the circle.
x^2 + y^2  10x  8y + 29 = 0
A. (x  5)^2 +(y  4)^2 = 12 (5, 4), r = 12
B. (x  5)^2 +(y  4)^2 = 12 (5, 4), r = 2 sq rt 3
C. (x + 5)^2 +(y + 4)^2 = 12 (5, 4), r = 2 sq rt 3

Best ResponseYou've already chosen the best response.0start with \[x^2 + y^2  10x  8y + 29 = 0\] then group the terms together as \[x^210x+y^28y=29\] to complete the square, take half the coefficient of the \(x\) and \(y\) term and write \[(x5)^2+(y8)^2=29+5^2+4^2\] then compute the number on the right

Best ResponseYou've already chosen the best response.0you get \[(x5)^2+(y4)^2=12\] so the circle has center at \((5,4)\) and radius \(\sqrt{12}\) or \(2\sqrt{3}\) if you prefer
