If the quadratic formula for a quadratic yields a single Real value, the the quadratic has one real zero (and no complex zeros).

#### Explanation:

Within the quadratic formula, the discriminant,

#{: ( > 0, rArr, "two Real roots"), ( = 0, rArr ,"one Real root"), (< 0,rArr,"two Complex roots") :}#

An examination of the quadratic formula:

should make the reasons clear.

If

one with a component

one with a component

If there is a single solution then
