Can anyone help me with solving this polynomial question? Use a horizontal format to find the sum. (12x^2-x)+11x^3+(-9x^3+x^2-7)

    I was told to combine like terms, and to work it out like it's written. We haven't learned anything about vertical format yet. I still cent seem to answer it correctly haha.

    so u know those tiny numbers i forgot wht they are called but whtever those stop numbers from making them into like terms, so when u add those things u basicially make it into vertical and add the numbers in this case
