Can any one solve this?

Find the y coordinate for the center of the ellipse given by the equation 8x^2 + y^2 - 4y = 2

[Astronuc]

Try to rewrite the equation in the general form of an ellipse.

A (x - x0)2 + B (y - y0)2 = 0,

where the center is at x0, y0

i don't know how. how do you write it?

[HallsofIvy]

Do you know how to "complete the square"?

[chaoseverlasting]

There is an easier method if you know differentiation. Differentiate the equation wrt x treating y as a constant to get a value for x, and similarly for y by treating x as a constant. The values of x and y you get are the coordinates of the center.

the center is at (0,3)
