Question 56782This question is from textbook College Algebra
: I am trying to find all zeroes of P(x) = 6x^4 - 7x^3 - 8x^2 + 5x.
Using synthetic division, I see that the upper bound is 2 and the lower bound is -2.
Using Descartes rule, I found that there are 2 or 0 positive real zeroes and 1 negative real zero. Is this correct? Because shouldn't there be 4 zeroes altogether due to the leading coefficient having a degree of 4? And complex zeroes only come in two's (pos & neg), so I have no way to combine these options to create 4 zeros. Where have I gone wrong?This question is from textbook College Algebra
