You mean to factor `(x+1)^2`
Both brackets on right side is simple form . So factor is complete.As for your answer (2x+1) it is ot correct.
Sorry I meant how do you factor (x+1)^2 - x^2
`(x+1)^2 - x^2` spread the exponent to the numbers in the parenthesis you will end up with:
it seems like you are right because based on my calculations you will end up with 1 if you were to ever solve for x and not 1/2 as the result of the problem you are doing would suggest, the guide is wrong
