i never used it before although im a 2nd year math student

Seppuku is the only way out.

In what, elementary school?

university, lol. I can do mutivariable calculus, but not this, please help and dont make fun im trying to learn

Once again, plug in the values to the quadratic equation.

Holy sh!t. If you're taking multivariable calculus (Calc 3 in my school) and you don't know how to use a graphing calculator, let alone the quadratic formula, you are in serious trouble.

BullSh1T you cannot do multivariable calc.Without KNOWING MOTHAFVCKING HIGHSCHOOL ALGEBRA.I AM A MATH MAJOR. BE QUIET DO NOT SAY THAT YOU ARE A MATH MAJOR.WHY AM I YELLING?

aaaaaaaaaaaaaaaaaaaaaaaaa, youre making me mad, all i need is a way to do this using graphing calc, i know lots more methods.

I am sorry for my above ouburst.I should realize that if he cannot use the quadratic or a graphing calculator, that he will soon fail and that the business shcool will have a new student.

Just use the solver if you have no idea about the bounds.

Like what using Cauchy Contour Theorem.

you have to be sh!tten me. geesh...you are in a calc class and you do not know the quadratic equation? You don't even need a calculator to do it.

PS How come no one will help me with my transistor question

actually, from what my g/f tells me, you need to know how to do stuff on the clac in business school.

True.I tutored BCal.I actually liked it... got lots of Sorority girls #'s

I know how to do a quadratic and qubic and etc.. without calc
but i need a quick way using calculator aah arh arg

I wrote this for my quadratic function on my TI-83 Plus way back.

Prompt A,B,C
(-B+(B^2-(4*A*C)0^0.5/(2A)->X
(-B-(B^2-(4*A*C)0^0.5/(2A)->Y
Disp X,Y

You can find the commands in catalog.

Here you go you tremendous waste of space.

OK, put it in y= again and make your left bound -10^99 and your right bound 10^99 and make your guess 0.

That will solve it... eventually
