how do you get the greatest common factor
Could I also use a -2 as the factor outside the parentheses? Does it have to be a +2?
I dont understand how 1+2(-x+2) in step two was reached
can you expand
Can you please explain this problem in more detail one how you did steps 3 and 4?
{ x|x E N and 82 < x < 87 }
I dont understand the problem
reducing the fraction to lowest terms
how did you change b to -b
When solving inequalities, we flip the sign when dividing... is that correct?
