I seriously don't get why you are still arguing with me lool.

[quote=opmeTK]don't know what state you live in, but until my AP Calc course, we were able to use calculators on tests and quizzes.[/quote]

Well most teachers don't allow graphing calculators on test and quizzes cause you can store information on there and some people use it to cheat.

The almighty Quadratic Formula.

x=[-b +or- (sqrt b^2-4ac)]/2a

@monkey3842: You're assuming he first started learning. Logic

@crazypoorer: When did I assume? I suggested he may be 10 years old [b]or something[/b] loool i don't get why you are arguing with me. As I said, not everyone knows the quadratic formula when they first start learning.

[quote=monkey3842]Not really... for all we know he may be 10 years old or something. Everything is always hard when you are learning it for the first time.[/quote]

So you can assume he's 10 years old, but you can't assume he's 12 years old or higher? Makes sense.

-3q^2 + 6q + 5 = 0
As you can see in this equation, it can't be factored easily, so you must use the quadratic equation.
* remember to replace "x=" with your variable! (in this case it's a Q)
q = -6 +- sqrt ((6)^2 - 4 (-3) (5)) / 2 (-3)
q= - 6 +- sqrt (36 + 60) / -6
q = - 6 +- sqrt (96) / -6
If you are in 10th grade, then the answer would be:
q is a product of (-6 - sqrt(96) / -6, -6 + sqrt(96) / -6)
If you are in 11th grade you need to simplify the radical (96 in this case)
q = - 6 +- sqrt (16) sqrt (6) / -6
q = -6 +- 4 sqrt (6) / -6
q = 2 (-3 +- 2 sqrt (6)) / -6
q = -3 +- 2 sqrt (6) / -3
Then the answer would be:
q is a product of (-3 - 2 sqrt(6) / -3, -3 + 2 sqrt(6) / -3)

You do know something's wrong when you don't know how to use the Quadratic formula

have fun.

[quote=crazypoorer]1) Spend $100 on a graphing calculator
2) Input the equation
3) Graph the equation
4) Find the zeroes
5) Now you know how to solve for zeroes[/quote]

[quote=LowWillpower]You must have learned quadratic formula. If so, you should have already learned a few other ways to solve parabolas too. I don't know if anyone here is going to do your homework.[/quote]
The person below you apparently will.

quadratic formula
answer when + = -0.633
answer when - = 2.63
if you want the work just ask

@lowwillpower hello

You must have learned quadratic formula. If so, you should have already learned a few other ways to solve parabolas too. I don't know if anyone here is going to do your homework.
