What are the possible rational zeros of f(x) = x4 + 2x3 − 3x2 − 4x + 12?
Asked by maham237 @ in Mathematics viewed by 298 People
Answered by maham237 @
I believe it would be the first term over the last term, +/-, including the factors of both the last term, so:
for x^4:
1*4
2*2
for 12:
1*12
2*6
3*4
then divide all of this, and include the +/-'s of each. By divide, I mean take all the factors of the first term, aka the numerator, and those are possible rat. 0's. Then divide all those by the factors of the coefficient. Remove any duplicates.
