If x^2 +4x +6 is a factor of x^4 +rx^2 +s, then r+s is:
One of us obtained 32, while the other got 52. I would just like to see what the correct answer is.
All exponents are all just the single number.
I never will understand this sort of dispute. This is not meteorology where certain signs may mean rain or they may not. One of you should be able to prove your answer. Who tried? Who succeeded?
Ignoring all the variables...
(1 0 r) - (1 4 6) = (0 -4 r-6)
(-4 r-6 0) - (-4 -16 -24) = (0 r+10 24)
(r+10 24 s) - (r+10 4r+40 6r+60) = (0 -4r-16 s-6r-60)
-4r-16 = 0
s-6r-60 = 0
