Text: Use the rational zero theorem to list the possible rational zeros: 𝑃(𝑥) = −𝑥^4 + 2𝑥^3 − 5𝑥 + 4
Added by Scott F.
Step 1
Step 1: The rational zero theorem states that if a polynomial function has a rational zero, then that zero must be of the form p/q, where p is a factor of the constant term and q is a factor of the leading coefficient. Show more…
