Question

Simplify the difference (-7p^4+4p^3+6)-(3p^3-5p+3)

I removed the parenthesis and changed the addition and subtraction signs to their opposites on the second set; -7p^4 + 4p^3 + 6 - 3p^3 + 5p - 3. When I combined the like terms, I was able to simplify the polynomial to p^3 + 5p - 7p^4 +3, this being my final answer. Am I correct?

Answer 1

Please help, I would really appreciate it.

Answer 2

Correct, but it is customary to write in descending powers:

-7p^4 + p^3 + 5p + 3
