Hi, i am in desperate need of in math. i am utterly clueless when it comes to math. civics on the other hand. i need with factoring in group. i am desprate and tired
5x^4-35x^3-x+7

First your going to use commutative property to reorder the terms , so it would be
5x^4-x-35x^3+7 , then your going to factor out x & -7 from the equation once you factor that out you should have x(5x^3-1)-7(5x^3-1) after you got that your going to factor out 5x^3-2 and get the answer (x-7)(5x^3-1) which is your final answer.
