| First, I want to reiterate what hoosierlaw said: the answer to #1, as it is written, is -77 and not 85. If you change the problem to read (-x)^4 in front, then it will be 85, or you can just change the answer to -77.
Second, no akabuca96, a polynomial (of a single variable) is any sum of powers of the variable, which is precisely what is in these problems- it has nothing to do with solving vs. simplifying. |
