I specifically said in my answer that I ended up not having to use a table to solve the equation. I also stated that your answer didn't help me to understand in finding the answer, I understand and agree with not giving users the answer but I was very confused on how to solve f(x)=g(x) and would have made a lot more sense if you had shown how to solve the X or variable in for the first column. I only understood what you were trying to do until I got help understanding everything by my sister and father. And I don't find downvoting your answer as rude because I didn't find your answer super helpful, and for the fact that you said "Please no one answer over me" when this is a website where anyone is free to answer and if someone doesn't understand the answer given then another can give a better response. I'm sorry for not editing my question right away, but by that time I had already gotten help so I didn't ask for more clarification. I primarily downvoted because other users and myself shouldn't need to ask for a lot of clarification especially when the question locks and sometimes a user can't, and I answered myself for other users who would have a similar question. I hope you can see where I'm coming from and I don't mean to offend you but isn't this what the positive and negative like buttons are for? I really do love this site because it's very reliable and quick, I appreciate all the top users, including yourself, that answer and help me to really understand and learn math. I hope you have a great day and I really do appreciate all that you do. Thank you for taking the time to answer my question and I sincerely hope you can see this situation from my point of view.
Im the creator of this question and wanted to solve it for anyone who needs help with a similar question because I didn't really understand Melody's answer. This was on of my practice questions on my study guide and found out later that my teacher said we didn't need to use a table of values so I solved it with my sister's help. :)
So it's a lot like algerbra except a lot more annoying in my opinion because i struggle with factoring. So you start by setting everything etting everything to zero.
Subtract x and ad 2 to both sides to set the equation equal to 0
\(x = 5, 2\)
Really hope this helps anybody struggling with this. Can't 100% confirm this is right because this is my own work BUT this is how I got my answer for this question.
1.(f+g)(x) = This is fairly simple, all you do is add the two problems.
x2 + 7x + 12 + x2 + 8x + 16
2.(f-g)(x) = Same thing here, just subtract the two equations.
x2 + 7x + 12 - x2 + 8x + 16
This is all combining like terms and simplifing. I highly recommend you use www.mathway.com to help you.
Hope this helps! Have a great day!!!
