Theorem. Let p(x) = anr" + … + ao be a polynomial with integer coefficients, i, e. each ai E Z. If r/s is a rational root of p (expressed in lowest terms so that r, s are relatively prime), then s divides an and r divides ao Use the rational root test to solve the following: + ao is a monic (i.e. has leading coefficient 1) polynomial with integer coefficients, then every rational root is in fact an integer....

in this problem I have a problem understanding the exact steps, can they be solved and simplified in a clearer and smoother wayTo understand it . Q/ How can I prove (in detailes) that the following examples match their definitions mentioned with each of them? 1. Definition 1.4[42]: (G-algebra) Let X be a nonempty set. Then, a family A of subsets of X is called a o-algebra if (1) XE 4. (2) if A € A, then A = X...
