Using the following equation, find the center and radius of the circle. you must show all work and calculations to receive credit. x2 + 2x + y2 + 4y = 20

In order to find the radius and the center of the circle we need to convert the given equation into standard form.the above equation is the standard form of the equation. from the above equation we can write the center of the circle to be (-1, -2) and the radius 5.so, center = (-1, -2)radius = 5
