Root for the first polynomial are gonna be
In this case
Solve number 2 and 3 with the same technique.
Once a root works, use the division to get the next polynomial.
So basically I had a make up test in Pre-Calc and right now I feel like ripping my hairs out for I have no idea if I got certain questions right. Any help will be appreciated. Thanks in advance
From the top of my head I remembered certain questions such as:
1) You have 2x^4+3x^3+7x^2-7x-5
I had to find the root now was I supposed to use the basic p over q and plug in which were correct roots?
2)This one killed me
I had to find the smallest root?
3) This one also confused me and I could not answer. It gave me two roots 2+i and 3. I was supposed to find out the cubic polynomial. How exactly is this done?
Thanks in advance for anyone who is willing to help.
