if you simplify an algebraic fraction that there is a binomial = numerator
polynomial = denominator

Now i saw a q, it asked for x values that are not valid.

So if an algebraic fraction not valid, it means it doesn't work so 1/0 values

Now, its simple ( ) ( ) ( ) poly factors,

well the simplfied version has ( ) ( ) meaning one factor cancelled.

Therefore to answer the x values invalidity, i do not refer to the simplified value, as it did not contain the other x value? I gave 2 x values from simplfiied fraction - i was looking there
