Question 288561
The discriminate is the stuff under the square root:

{{{b^2-4ac}}}

In your case: a=9, b=-7, and c=5

Put these into the discriminant equation to get:

{{{(-7)^2-4(9)(5)}}}
={{{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.
