Question

find all the zeros of this equation
f(x) = 3x^3-7x^2+6x-8
please show work.

Answer 1

best bet is to factor by grouping

Answer 2

(3x^3-7x^2)+(6x-8), it is a start

Answer 3

oh okay. I guess that's all I really needed to know.

Answer 4

Finding zeros is a pain. First find the possible rational zeros, then test them to see if one will turn up a zero

Answer 5

this is real and non real though. The idea is to find 3 zeros so that we understand that the degree usually determines the # of zeros

Answer 6

For this equation: \[3x ^{3}-7x ^{2}+6x-8\]
p= \[\pm1,\pm2,\pm4,\pm8\]q=\[\pm1,\pm2\]
these are the possible zeros
then do p/q, make a chart and plug the p/q values in.

Answer 7

thank you :)
