Question:
I am using Houghton Mifflin's Precalculus with Limits book, 2nd edition.
However, the first chapter encompasses Algebra review, and I am stuck
on a problem. All that's required is to solve the following and verify
using
a calculator:
3y^{2}+6y+2=0
I have solved the problem using the quadratic formula, but from what
I remember, the quadratic formula is used in the case of equations
following
the AX^{2}+BX+C=0 pattern. As the problem I am attempting uses a yvariable,
can I still use the quadratic formula? Since I am not sure what route
to take in solving this problem, I am hoping you can assist me.
Thank
you.


Hi,
The quadratic formula is valid, regardless of the letter
you use for the variable. At times in my classes I use a question mark
rather than
a letter, to emphasize that the symbol stands for something I don't know.
3?^{2} +6? +2 = 0
