What is the general form of a quadratic equation?

Back

The general form is y = ax² + bx + c, where a, b, and c are constants and a ≠ 0.

How can you determine the number of solutions in a linear-quadratic system?

Back

By finding the points of intersection between the linear and quadratic graphs; the number of intersection points indicates the number of solutions.

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

What is the significance of the discriminant in a quadratic equation?

Back

The discriminant (b² - 4ac) determines the nature of the roots: if positive, two real solutions; if zero, one real solution; if negative, no real solutions.
