Identifying conic sections from their expanded equations
Learn how to analyze expanded equations in order to determine which kind of conic section they represent.
Sal manipulates the equation 9x^2+4y^2+54x-8y+49=0 in order to find that it represents an ellipse.
Sal manipulates the equation 4y^2-50x=25x^2+16y+109 in order to find that it represents a hyperbola.
Sal manipulates the equation x^2+y^2-3x+4y=4 in order to find that it represents a circle, and the equation 2x^2+y+12x+16=0 in order to find it represents a parabola.
