You can put this solution on YOUR website!
The discriminate is the stuff under the square root:
b%5E2-4ac
In your case: a=9, b=-7, and c=5
Put these into the discriminant equation to get:
%28-7%29%5E2-4%289%29%285%29
=49-180
=-131
The discriminant is negative, which means it has no real solutions. There is a complex solution. On a graph, it would not cross the x-axis.
