how do you factor the difference of squares
I get -8??
I dont understand the step where the 9 is removed
how did you get 45-x
I need this simplified
how did you come up with 3-1?
How did you multiply x+ 5 by 9 and get x+5?
Can you please explain it in more clearer terms please?
Are there steps to see how this is simplified to 1?
Im super stuck on this one
