Set 14: Quadratic Equations (Advanced)

Choice A is correct. Choice A is the correct answer. When solving a system of a linear and quadratic equation, you get a new quadratic equation. * 2 Intersections $\leftrightarrow$ 2 Real Solutions $\leftrightarrow$ Positive Discriminant. * 1 Intersection (Tangent) $\leftrightarrow$ 1 Real Solution $\leftrightarrow$ Zero Discriminant. * 0 Intersections $\leftrightarrow$ No Real Solutions $\leftrightarrow$ Negative Discriminant. Choice B is incorrect because zero means 1 point (tangent). Choice C is incorrect because negative means 0 points. Choice D is incorrect.
