It is a binomial, which is also a polynomial.
4
2n + 4m - 2n + m = 5m
Divide all the terms by 4:- 2n2-9n+10 = (2n-5)(n-2) when factored
2n plus 4 = 2n + 4
(m - 6n)(m + 2n)
(m + 2n)(m - 6n)
4n
7+2n
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
Exactly that. 2n+2.
(2n + 7)(2n + 7)
15m + (2n-6m) + 11m = = 15m + 11m + 2n - 6m = 26m - 6m + 2n = 20m + 2n = 2(10m + n)
