Determining Values for A, B, and C in Quadratic Formula
I have a question:
For the quadratic equation (2x+1)(x+3)=0, does 2=a, 1=b, and 3=c?

The ZeroProduct Property tells us that
x + 3 = 0
OR
2x + 1 = 0
Let's solve x + 3 = 0.
Subtract 3 from both sides
x = 3
There's one answer.
Let's solve 2x + 1 = 0
Subtract 1 from both sides then divide both sides by 2.
x = 1/2
There's the other answer.
Now, if you still believe that using the Quadratic Formula is an easier way to get
x = 3 or x = 1/2
then I must tell you that you are entitled to your opinion.
Cheers
