5x^4−30x^3−35x^2, x^5−a^3x^3−b^3x^2+a^3b^3

So I factored it, and I got 5x^2(x+1)(x-7), but my webwork is keep saying me to factor them out completely.

I wonder if they wanted the 5x^2 entered as 5xx.

5x4 - 30x3 - 35x2 = 5x2(x2 - 6x - 7) = 5x2(x + 1)(x - 7)


I got the same result as you. Is there a special format in which you need to upload the answer?

Thank you! No there's not. I guess I'll talk to my professor about this.

Yes, take this up with your teacher. Sometimes there are "bugs" in those online learning tools.
