Ok, I am trying this again, can you please tell me if this is correct or anywhere close to what I am trying to accomplish? Thanks
I have come up with 2k(2+k^2+2k) I don't feel confident that it is anywhere close to what I am suppose to have.
On this problem why is it that the 9 seems to disapear? It seems to just drop off????
My final answer was 2y(y-2)(y-7)=0
Where did the 9 go to?? I don't understand it but I think I got it right.
Here's how it goes:
When you factor the trinomial, the sum of the two factors that make 14 must add to make -9.
You see. The -9y is made up of -7y + -2y. You may see it better this way.
Here, I just replaced the -9y in the middle with the sum of the two factors that made +14. Now, if I group the 4 term polynomial, I arrive at the desired factored result.
