Then the quadratic formula can be used to solve for y. The general form of the conic, Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, can be rearranged to Cy2 + (Bx + E)y+(Ax2 + Dx + F) = 0. Note that this now has the form of a quadratic in y. Applying the quadratic formula gives . There is one problem with keying in this formula, there is no “±” button.
