If the m-th power - (n-1) x + 1 of the polynomial 3x is a quadratic binomial of X, the value of M and N can be obtained As long as the answer. You have to explain under the line. Will be chasing points
Obviously, the second term of the second power means that the highest power is 2, which is m = 2
Two statements have no one term, that is, n = 1
