## Step 2: Downloading Your FREE Program to Test TI84programs.com

You can click on this link to download your free copy of quad program. Even if you don’t care at all for quadratic equations, it’ll prove to you that you can download programs from TI84programs.com and use them. More importantly, you’ll see what they can do. Some programs show only basic formulas, such as area, perimeter or volume. Other formula programs can display equations as complicated as trigonometric identities or derivative and integral formulas. Another type of program can actually solve basic algebraic equations along with other applications. More on that later at TI84programs.com

Once you download the program, which you can do so as a Zip file, you’ll have to unzip or decompress it. You’ll see it as QUAD.8xp.zip and you want it as QUAD.8xp

From your desktop, make sure you see QUAD as a .8xp file. Then, with your TI Connect CE application open, click and drag the QUAD.8xp file onto the calculator. You’ll see this window open up asking if it’s ok. Please reassure TI Connect CE that it’s okay.

Then, on your calculator, you can press the Program key. It has prgm on it and is located on the upper middle part of your ti84 calculator keypad. Basically, it’s 3 keys above the 8 key.

**Using Your QUADFORM Program**

Once you press PRGM, you might jump to your programs. But, with the more recent operating systems from TI, you’ll be asked TI-Basic or Python App. For now, let’s choose TI-Basic.

Then you’ll see a list of the programs you have on your connected calculator. You can either scroll to the name of the program you want or press the corresponding number or letter immediately to the left of the program name.

Wait, you’ll also have to press Enter to run it. The first keystroke was to select it. The ENTER keystroke is to run it.

Now, you’ll see this, the standard form of a quadratic equation. Just to make sure your program works properly, you can enter 1 for A, 5 for B, and 6 for C. That’s equivalent to 1x^2 + 5x + 6 = 0. The program will provide you with the 2 answers of x1 as -2 and x2as -3. The bonus is the answers in the format of the discriminant form: -5 plus or minus -1 divided by 2.

Even if you don’t care a wit about the quadratic formula, at least you know now that you can download functional programs from TI84programs.com

Many programs will show only formulas, while others will actually solve problems. Both kinds are available at TI84programs.com We have a growing library of programs available on site. Also, you can check our YouTube channel for updates. Or, if you’re more interested in social media, we have some channels there as well.

Thank you for following along with this process. After this, downloading and using ti84 programs from ti84programs.com will be a much simpler and faster process for you.
