Or, more briefly, x = {q + [q 2 + (r-p 2) 3] 1/2 } 1/3 + {q - [q 2 + (r-p …
WebJul 12, 2024 · The Factor and Remainder Theorems. When we divide a polynomial, p(x) by some divisor polynomial d(x), we will get a quotient polynomial q(x) and possibly a remainder r(x). In other words, p(x) = d(x)q(x) + r(x) Because of the division, the remainder will either be zero, or a polynomial of lower degree than d (x).
WebSay you plug in a and it solves the polynomial. Then the polynomial x − a must divide x 3 − 3 x 2 − 320.
