Question about Texas Instruments TI-89 Calculator

1 Answer

Expand? When I hit Expand (x-5)^3 I get (x-5)3 which is not what I am looking for. I have spent hours looking for the solution and haven't gotten anywhere.

What you're typing in and thus asking for is the cube of the expansion of (x-5), and that is exactly what the calculator is giving you. The expansion of (x-5) is (x-5), of course, and the cube of that is (x-5)^3.

What you want is the expansion of (x-5)^3. To get this you need one more set of parentheses.

expand((x-5)^3)

Note the two open parens immediately after the "d".
