how do you do a quadratic equation without a b value?
All quadratics have a b value but sometimes the b value is zero and, in fact, sometimes the c value or a a value is zero. If the a value is zero, I believe that it ceases to be a quadratic.
In other words:
Ax^2+C=0 can be written as:
Ax^2+0x+C=0 solve using the quadratic formula
