Number of x-intercepts
Number of x-intercepts is a skill on Pengi from Lesson 5: The Quadratic Formula in Yoshiwara Elementary Algebra.
Key Concepts
Property The $x$ intercepts of the graph of $y = ax^2 + bx + c$ are the solutions of $ax^2 + bx + c = 0$. There are three possibilities:.
1. If both solutions are real numbers, and unequal, the graph has two $x$ intercepts.
2. If the solutions are real and equal, the graph has one $x$ intercept, which is also its vertex.
