I have a question:
For the quadratic equation (2x+1)(x+3)=0, does 2=a, 1=b, and 3=c?

Of course he means multiply! Have you not learned FOIL yet?! :cool:
PS: I split your previous thread. Note the useful subject line.
What grade are you in now?
Okay, I did the FOIL method, and got:
2x^{2}+7x+3 :)
2=a,7=b, and 3=c
Right? Please say yes.
Yes.
Are you thinking that you need to use the Quadratic Formula to solve the equation (2x+1)(x+3) = 0 ?
If so, I would like you to know that there is a much simpler method that uses something called the Zero-Product Property.
