Quadratic formula

That was a awesome post. Couldnt say it near as well but thanks. Spent time with Vinny, its easy if I can memorize the two formulas and just stop questioning why I need to memorize two formulas, now I just need to memorize them, and Im practicing some things he taught me in regards to other algebra, .....

:)



Well, IMO (as a teacher for 35 years) your problem is right there. If you treat mathematics as memorizing formulae you will never get very far because there's just too much to memorize. If you try instead to understand the basic principles, everything builds on them in a logical fashion and you don't have to remember so much.

Deriving the quadratic formula:

1. A quadratic equation is one that can be put into this general form:

aX**2 + bx + c = 0, where a, b, and c are numbers and x**2 means x to the second power or "x squared".

Keep in mind that the equations you see on a test might not look exactly like that. To solve some equations you need to manipulate the equation to get it into that form. For example:

3x**2 = 20

In this case you need to first subtract 20 from both sides, giving you:

3x**2 - 20 = 0

Why do that? Because to use the quadratic formula, one side of the equation *must* be zero. The above equation is in the form ax**2 + bx + c = 0;

a = 3, b=0, and c=-20

Are you with me so far?

tnhat works fine and dandy when you have the time and patience to go way back and re-build (or in my case initiALLY BUILD) THOSE FOUINDATIONS oops my big problem with Maths is that the teachers who taught me were crap at teaching, (if you dont understand what in the book I'll read the words to you, if you still dont understand I speak LOUDER:S:S) consequently my maths sucks arse, but If i can use the formulae, i can blunder my way through

TAKE YOUR NUMBER OFF THE MAIN THREAD pleaseeeeee

Im actually getting it a bit, dont have the quad memorized yet but im fine tuning the factoring. Ill get through the test and pass. I wont have a A and Ill never quite understand most the stuff I have to learn but it is what it is.

LoL, I learned my lesson since then! Yes, I do know now that "fine for parking" doesn't mean it's ok to park there!

No you didnt? For realLaughLaughLaugh



ok ok... here's the story:

I was 16, and it was my first time driving to nashville by myself to go to non-christian bookstore... something which was forbidden by my parents. I was so excited/nervous...ect. I was driving around looking for parking and couldn't find parking. I then saw this huge space with a sign right by it saying "fine for parking." I was like, "rock on!, I can park here... sweet." So I parked there, and right as I'm parking, a cop car comes right behind me and flashes his lights. He came up to my door and asked for my driver's license and what not. He then told me he was going to give me a ticket if I parked there. I was flabbergasted and told him that the sign said I could park there. He looked up and read the sign then said, "well let's read the sign together." We both chime in and said "fine for parking"... and I was like "see... I can park here." He then went to his car for a few minutes, got on his radio... then came back to my car shaking his head, returned my license and told me to just go and park somewhere else. I then called a girlfriend and told her what happened... and that's when I found out what the whole fine for parking sign meant.....

haha, I'll never live it down, but it's a funny story now!!
