    why at 9:08 does x-2 become x+2 when the parenthesis are dropped? 5 5(x^2 -4)-(x-2) = 5x^2 -x-2 doesn't it? It has been a long time since I've done math and I'm here for review before a placement exam so I'm only asking to know if I am forgetting about some simple rule that i should know about.

    Pleas help... at 12:30 the last answer.... how come the top (x+2) did not cancel out with the other one to make zero. and on the bottom there were two (x-2) 's should this have been squared... Confused.. thanks in advance.

    The x-2's were all in the denominator as with the x+2's all on the numerator. You can cancel is one x-2 is on the numerator and on on the denominator. As well as the affirmentioned x+2. Youre welcome.

    You cant cancel the y since the other y in (20+y) is with a operation +or -. In other words, you cant cancel if the variable or number is with or in an operation. (+ and -) but you can cancel if its multiplication

    at 10:00 you could just to factoring by grouping so that its going to be easier. (7x^2 - 28) + (2x+4) divided by (5x^2 - 20) - (x+2) then 7 (x^2 - 4) + 2 (x+2) divided by 4 (x^2 - 4) - 1 (x+2) cancel out like terms and it is equal to 9/6 = 1 1/2

    if he divided X^2 by just “X” it wouldn’t simplify to a whole number, it would simply to 1/x which isn’t getting rid of the fraction
