OpenStudy (marinebaby):
Is it true that (x^2-3x+2)/(x-1) = x – 2, for all values of x? Can someone show me how to justify this? No idea where to start!!

Keep in mind that if you have that (x-1) in one term of your equation, x can NOT be 1. Think about this. Why is that so?
OpenStudy (marinebaby):
uhhh im not sure. why can't it be 1?
OpenStudy (jay-bird):
The best way to justify is generalisation, so replace x and x-2 with letters, and use general algebra to show that it would always/ not always equal x-2
