I am having trouble on this problem! I need to factor this problem...x^4-(x-1)^4
I then simplified it to....(x^2)^2-((x-1)^2)^2...is this correct and if so I don't know what to do next!

a[sup:eek:x20ga07]4[/sup:eek:x20ga07] - b[sup:eek:x20ga07]4[/sup:eek:x20ga07] = (a[sup:eek:x20ga07]2[/sup:eek:x20ga07])[sup:eek:x20ga07]2[/sup:eek:x20ga07] - (b[sup:eek:x20ga07]2[/sup:eek:x20ga07])[sup:eek:x20ga07]2[/sup:eek:x20ga07]

Now use

a[sup:eek:x20ga07]4[/sup:eek:x20ga07] - b[sup:eek:x20ga07]4[/sup:eek:x20ga07] = (a[sup:eek:x20ga07]2[/sup:eek:x20ga07])[sup:eek:x20ga07]2[/sup:eek:x20ga07] - (b[sup:eek:x20ga07]2[/sup:eek:x20ga07])[sup:eek:x20ga07]2[/sup:eek:x20ga07] = (a[sup:eek:x20ga07]2[/sup:eek:x20ga07] + b[sup:eek:x20ga07]2[/sup:eek:x20ga07]) (a[sup:eek:x20ga07]2[/sup:eek:x20ga07] - b[sup:eek:x20ga07]2[/sup:eek:x20ga07]) = (a[sup:eek:x20ga07]2[/sup:eek:x20ga07]+ b[sup:eek:x20ga07]2[/sup:eek:x20ga07])(a + b)(a - b)

In your case, you'll have further simplification to do....



and if so I don't know what to do next!

so now i got....[x^2+(x-1)^2] [x+(x-1)][x-(x-1)]...is this right?<< Yes but you need to simplify further inside those [].
