Answer 2

Hi!

Positive discriminants will give you two solutions.

Discriminants equal to zero will give you one solution.

Negative discriminants will give you no solutions.

In a graph, the number of solutions is where the graph crosses the x-axis.

In the first graph, we can see it intersects the graph at two points: (2, 0) and (6, 0). Since there are two solutions it is a positive discriminant.

In the second graph, we can see it intersects at one point: the origin, or (0, 0). Since there is one solution it is a discriminant equal to zero.

In the third graph, we can see it doesn't intersect; it is above the x-axis. Since there are no solutions it is a negative discriminant.
