Practise conic sections — finding a circle's centre and radius by completing the square, a parabola's vertex, and an ellipse's axes and foci — with clean, printable worksheets and a full answer key.

x² + y² − 10x + 16y + 53 = 0 — centre & radius

Show answer

(5, −8), r = 6

y = 2x² + 16x + 24 — vertex

Show answer

(−4, −8)

x²/625 + y²/49 = 1 — a, b, c & foci

Show answer

a = 25, b = 7, c = 24, (±24, 0)
