Question

For the polynomial –2m2n3 + 2m?n3 + 7n2 – 6m4 to be a binomial with a degree of 4 after it has been fully simplified, which must be the missing exponent on the m-term?

Answer 1

notice how the 2m^2 * n^3 term has a degree of 5
so for the entire polynomial to have degree 4, we have to cancel out all the m^2 * n^3 terms somehow

what exponent could you put in the question mark spot to result in all the m^2 * n^3 terms being cancelled out?
