Anon2121: n^2-8n-49=-5
First I want you to learn to use the 'sup' button that is located above the smilies.
If you want to enter n^2 you do it like this
n now press the 'sup' button. The curser will be placed where you need to enter the 2. Now just move the curser to the end and keep going.
so your question is
n
2-8n-49 = -5
Whenever there is a squared term, you have to take it all over to the same side. (with 0 on the other side) You need to add 5 to both sides.
n
2-8n-44 = 0
Now, I don't think that this factors out nicely so it is probably best to use the quadratic formula.
If you dont know it, go to this web page and play the video. It is cool. I like it.
just copy and paste it into your browser.
