a) You actually let so that you get a quadratic equation in
.
Solve it for , then solve for .
b) and you know . Solve for . I think you'll also find that , not .
Solve:
a)
I know I have to make or something along those lines.
But I have no idea what to do next
Also,
Find the value of A, B, C if
So I expand the first one...
then
With this I know that A = 2 B = -4 but I can't figure out C. I get -2 but it's wrong. What did I do wrong?
ok, I get it now!
So
Here is another (sorry I'm trying to pick this up myself with only the textbook and I'm trying my best )
Find the value of A,B,C if
Expand:
I'm so sure what to do next so I group the terms into groups?
I'm pretty sure this is incorrect. Could someone help me out (not necessarily give me the answer)
Thanks for all the help!!!!
