It's just 3m + 2. Now, if m stands for a particular number, it's 3 times the number, plus two.

2m + 2 = 3m + 4 => 2m-3m = 4-2 => -m = 2 => m= -2
-3m + 8 = 2 -3m = 2 - 8 -3m = -6 m = -6/-3 m = 2
Without any equality signs the given terms can't be classed as equations.
37m squared
18m^2 - 12m + 2 = 2(9m^2 - 6m + 1) you can apply the formula (a - b)^2 = (a^2 - 2ab + b^2) or if you don't remmember it, continue to work: = 2(9m^2 - 3m - 3m + 1) = 2[(9m^2 - 3m) - (3m - 1)] = 2[3m(3m - 1) - (3m - 1)] = 2[(3m - 1)(3m - 1)] = 2(3m - 1)^2
