I know how to do some algebra equations but not all, i think this is a problem because im a freshmen in highschool and im not catching up in class

Hi John,

To solve this problem, first thing you'll want to do is multiply out the first set of parenthesis. So, you want to multiply (5x-2) times (x

^{2}-x^{3}). This gives 5x^{3}- 5x^{4}- 2x^{2}+ 2x^{3 = }-5x^{4}+ 7x^{3}- 2x^{2 }Now, take (-5x

^{4}+ 7x^{3}- 2x^{2}) and subtract (2x^{2}- 3x - 4). This gives -5x^{4}+ 7x^{3}- 2x^{2}- 2x^{2}+ 3x + 4Collecting like terms, we get -5x

^{4}+ 7x^{3}- 4x^{2}+ 3x + 4.
