Given a quadratic equation 
, we define the discriminant as
The number of real solutions of the equation depend on the sign of 
:
- If
the equation has two solutions - If
the equation has one double solution - If
the equation has no real solutions
In this case, we have
And so this equation has no real solutions.
Answer:
The corresponding segments AB and DC in the image are parallel.
Step-by-step:
It already tells us that segment QR is parallel to segment TS. So now the only segments left are segments AB and DC. Now look at segments AB and DC, do they look parallel? Yes, they do.
And that's how I got my answer. Even further, I took the test and got it right.
Your welcome. ;)
