teacher is telling me im wrong please someone show me where here is what I got using the column method add equations together 4x²-3x+7 3x²+4x-6 _________ 7x²-x+13 ending result cf of 1st & last term 7x²=(7x)(x) 13=(-1)(-13) 7(x-1)(x-13)
Your mistake is that you added them, where you should subtract.
You should multiply each term of the second parenthesis by -1 before you add the like terms to the the first parenthesis .

Does that help?
ty
You're welcome!
after multiplying by -1 and adding them together i got 7x^2-7x+13 which is the same answer I had to start with the teacher said was wrong
Look carefully!! It's not the same.
ur right I forgot about the -7x
so then this is the answer 7x^2-7x+13
Exactly!
do we factor it down any further
No, that's all. It can't be factored.
