Answer 2

can you use better notation to clear up any ambiguity

Answer 3

yeah i can post the link to the problem sorry

Answer 4

this would be true of the denominators are equal, right?

Answer 5

yes

Answer 6

x^2-7x+2 = x^2-2x+2

-7x+2 = -2x+2

-7x = -2x

-7x +2x = 0 when x=0

Answer 7

ok i understand that so what would be the answer undefined or 0?

that is when x=0

when x=0: 1/2 = 1/2 is true
