1. The problem statement, all variables and given/known data Find all zeros of k(x) = 4x^4-7x^2+3x 2. Relevant equations n/a 3. The attempt at a solution I don't know if I should find the factors of 0 and 4.. Can you help me what to start out with.. I can do other ones like p(x) = 3x^3-37x^2+84x-24. But this problem k(x) = 4x^4-7x^2+3x doesn't have the last number to factor. can't factor the 0..
