Explanation Definition used: Identifying a Conic Section from the Second-degree Equation: The second degree equation is of the form A x 2 + B x y + C y 2 + D x + E y + F = 0 . 1. If A = C , B = 0 , a circle . 2. If A ≠ C ( Same sign ) , B = 0 , an ellipse . 3. If A and C have different signs , B = 0 , a hyperbola . 4. If A = 0 , C = 0 , B ≠ 0 , a hyperbola . 5. If either A = 0 or C = 0 ( both not both ) , B = 0 , a parabola . Calculation: Rewrite 4 x 2 + 4 = 9 − 8 x − 4 y 2 as, 4 x 2 + 4 − 9 + 8 x + 4 y 2 = 0 4 x 2 + 4 y 2 + 8 x − 5 = 0 Note that, 4 x 2 + 4 y 2 + 8 x − 5 = 0 is of the form A x 2 + B x y + C y 2 + D x + E y + F = 0 where A = 4 , B = 0 , C = 4 , D = 8 , E = 0 , F = − 5 . It can be observed that A = 4 , C = 4 and B = 0 . From the above definition, it can be concluded that the equation 4 x 2 + 4 = 9 − 8 x − 4 y 2 represents a circle. Thus, the type of curve represented by the equation 4 x 2 + 4 = 9 − 8 x − 4 y 2 is a circle _
