Question

4x^2 − 4x + 4y^2 − 35 = 0

Determine the center and the radius for the circle. Also, find the y-coordinates of the points (if any) where the circle intersects the y-axis. (If an answer does not exist, enter DNE.)

Answer 1

Remember that the equation for a circle is:\[(x-h)^2+(y-k)^2=r^2\]

Answer 2

Will have to complete the square here.
