The first problem (m-2) is that the fifth power of (m-2) x-n + 1 power + 4x + n is a quartic trinomial (m-2) x ^ 5-x ^ (n + 1) + 4x + n is a quartic trinomial, m-2 = 0n + 1 = 4m = 2n = 3 (M + n) n power = (M + n) ^ n = 5 ^ 3 = 125, because the fifth power of (m-2) x-n + 1 power + 4x + n is a quartic trinomial, but one of them is the fifth power of (m-2) X
