Question

The equation of a circle is given as x2+ax+y2+by=c where a, b, and c are constants. The radius of the circle is given by the expression
(a2)2+(b2)2+c

a+b+c

(a2)2+(b2)2

c√

Answer 1

B because if the circle has a radius of x2 the 1/2 of that would be a+c bringing in c to become abc or a+b+c

Answer 2

Answering actually A
