Like i said before: quadratic equations are in the format:
I'm sure you understand that.
The quadratic formula:
Thats how the formula looks, and you have to learn that format.
Let's say we want to solve that equation at the top that i used to explain.
Then wherever there is an a, we substitute it with 2.
Wherever there is a b, we substitute it with 3.
Wherever there is a c, we substitute it with 4.
Do you understand?
To be a quadratic equation, it needs x^2 in it, where the power symbol ^ is used to mean that x is to the power 2.
