The function on a ti-89 that gives you the zeros of a quadratic equation is called just that "zeros". To access it from the home screen, press f2 and select the label called "zeros(" then type the function and define the variable. For example:
if you want the zeros of y=x^2+7x+12 you the display should read:
zeros(x^2+7x+12,x), press enter and it will give you the results in this case {-3, -4}.
We can check if it did it right by factoring this simple quadratic. 0=x^2+7x+12 factors as 0=(x+3)(x+4) set the factors equal to zero:
x+3=0 x=-3
x+4=0 x=-4
So we see that the calculator did it right! That is always a good thing. This will work for most polynomial functions.

How do you solve 2x squared plus 8x plus 5 equals 0?
By using the quadratic formula. -b +/- sqrt(b^2-4ac)/2a a = 2 b = 8 c = 5 -8 +/- sqrt(8^2-4(2)(5))/2(2) -8 +/- sqrt(64-40)/4 -8 +/-sqrt(24)/4 X = -0.7752551286 X = -3.224744871 my TI-84 graphing calculator confirms this. you may want that exact answer
Factor on the calculator?
graphing calculators only. TI-83 and TI-84 calculators.
How do you do an inverse log on a TI 30x?
On the TI-30x model there is no INV button. You have to use the 10^x function. To do this press the button labeled "2nd" and then the button labeled LOG. Above the LOG button you should see the 10x function which is the same for INV.

What number raised ti the fifth power equals 3125?
55 = 3125 5 x 5 x 5 x 5 x 5 = 3125 The answer can be obtained via a calculator or by the use of logarithms.
Where can someone find information on quadratic equation solvers?
If you are looking to download an app on your ti-84 or higher calculator, you should watch the "Quadratic Formula Program on the Ti-84" on youtube. Best of Luck!
What is theDifference between ti 89 calculator and ti 89 titanium?
The Titanium version of the TI-89 is a better version of the generic TI-89. It boasts more RAM, a more robust math function library, and a mini-USB port.
Who uses TI BASIC and what is its purpose?
The purpose of TI BASIC is to create math-oriented programs. It is exactly the same as what you normally input to do math, only with the addition of loops and other programish things. A big favorite is the Quadratic formula program, in which you input A, B, and C and it gives you the answers. I use TI BASIC to make my calculator do my homework for me.
How do you transfer apps from the TI-86 to the TI-89 Titanium?
i have no clue
How do you factor on the ti 84 calculator?
You cant factor on the ti-84. however the ti-89 does do this but its almost easier to just do it in your head. Plus on the ti-89 the way you enter it in there is a very high risk for error.

Which is better ti-89 or ti-84 plus?
The TI-89 is the better calculator. It has more functions than the TI-84, but is also more complex. Each is better for different situations or skill levels with calculators.

How can you expand polynomials in the TI 84?
Unfourtunately, it is not possible to expand with the TI-84. Only the TI-89 can expand polynomials.
How do you use the anti log on a TI-89 calculator'?
To find anti log of a number enter the number as the exponent of 10.
