X^2+2x+y^2=20 find the center and radius of the circle

Center: (-1,0)

Radius:

Step-by-step explanation:

You can complete the square for x:

The standard form for a circle is , where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius. Therefore, the center of this circle is at (-1,0), and the radius is . Hope this helps!

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
