For there to be just 1 solution, the part
of the quadratic formula called the
discriminant must equal zero.
The discriminant is:
The quadratic formula is:
when you are given the general form:
this is how you find a, b, and c
--------------------------
So, for 1 solution:
------------------
You are given:
and
and
If , there is only 1 solution
-------------------------------
check the answer
So, there is only 1 solution
