TI 89 for Statistics > How To Expand A Binomial On The TI-89
A binomial is a type of polynomial that has two terms (bi means two), usually joined by a plus or a minus sign. For example, 4x+10 and 3x-8 are both binomials. If a binomial has been raised to a large power, such as (3x-8)10 and you want to expand it, you could work it out by hand using the binomial theorem. However, this could take you several minutes. Expand a binomial on the TI-89 in seconds.
How To Expand A Binomial On The TI-89: Steps
Sample question: Expand the following binomial: f(x) = (2y+3)(5y+6)
Step 1: Press the HOME key.
Step 2: Press F2 and then press 3 to access the “expand” function.
Step 3: Press ( 2 y + 3 ) ( 5 y + 6 ) ) to enter the function.
Step 4: Press ENTER. Your answer will be 10y^2 + 27y + 18.
That’s it! You’re done!
