Just subtract the two. 10x^8 - -15x^8. The answer is 25x^8 because the two negatives come together to make a plus.
The answer is quadratic trinomial because it is to the power of 2, and has 3 terms.
You have two steps to do to complete this problem, combine like terms and simplify. You'll be simplifying (x−4x)+6x^2+8 to −3x+6x^2+8.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
