y2 – 4x2 – 4y + 8x = 4 is an equation of a/an: a) Parabola b) Hyperbola c) Ellipse d) Circle e) None of these
Added by Kayla R.
Step 1
First, we can rewrite the given equation as: y^2 - 4y + 4x^2 - 8x = 4 Now, complete the square for both x and y terms: (y^2 - 4y + 4) + 4(x^2 - 2x + 1) = 4 + 4 + 4 (y - 2)^2 + 4(x - 1)^2 = 12 Show more…
