## Algebra 1

In order to simplify, we want something to be both in the numerator and the denominator of the fraction so it can be canceled out. Thus, we factor and obtain: $2(x^{2}+x) / 3(x^{2} +x) \\\\ 2/3$ x cannot equal 0 or -1, for if x equaled 0 or -1, the denominator of the fraction would cancel out to 0, which is not allowed.
