6. Hello paulmdrdo,

We ask (as per forum rule #16) that math questions be posted in the appropriate sub-forum. I recommend posting this in the pre-calculus forum. This way, all members have a chance to read your problem and offer help, and it contributes to the knowledge base of our site.

Best Regards,

Mark.
