    Please tell me what conic sections these equations describe

    3x^2-5y^2+4x+y-10=0

    and Y^2 = -6x^2+36

    thank you.

    Hello, jhonwashington!

    3x - 5y + 4x + y - 10 .= .0

    It is already in standard form (all terms on one side).

    Since x and y have opposite signs, it is a hyperbola.



    y .= .-6x + 36

    Standard form: .6x + y - 36 .= .0

    Since x and y have the same sign, it is an ellipse.

    (Note: If x and y have identical coefficients, it is a circle.)
