The General Equation of Conic Sections

Question 10 • Precalculus

Which conic section is represented by the following equation?3x2 – 7x + 8y2 – 2y + 1 = 0

Answer
A
circle
B
ellipse
C
parabola
D
hyperbola

Explanation

The squared terms are 3x² and 8y², so their coefficients are both positive but unequal. A conic with squared terms of the same sign and unequal coefficients is an ellipse. Completing the squares gives a positive right-hand side, confirming this is a real ellipse, not a degenerate case.
