Look for common factors and divide them out of both numerator and denominator at the same time.
You know they're both divisible by 2, so you can simplify to 18/40.
As you can see, both numbers are still divisible by 2, so you can go down to 9/20.
At this point, they have no common factors, so the fraction is in lowest terms.

2. a zero discr. results in two real, equal roots.

3. a negative discr. results in two complex roots, which sometimes means two imaginary roots.
