| from the home screen f2 -> 2 takes you to algebra -> factor and you just type in the function. its the only argument you need. |

Sorry, I have it backwards. What I am trying to do is go from (X+3)(X+4) and get the answer X^2 + 7x + 12.
Thank again |

Thanks D, I have been trying to figure that out for a couple of weeks. I am sure you know but for someone who may not, I had to enter.
expand((x+3)(x+4)) |
