what is the sum or difference 2x^4-8x^4

Answer 1

The terms are the same (x^4) so you just combine the coefficient based on the sign between the numbers. In this case 2-8 = -6
so -6x^4 is the answer.

Note - you can only add/subtract apples with apples. So as long as the variables are the same, combine the coefficients
