To reduce a fraction, you need to rewrite both top and bottom in most factored form and then look for common factors on top and bottom to cross out. Use all of your factoring techniques, including finding greatest common factors, using the difference of perfect squares, looking for opposite binomials, factoring trinomials, etc. Once the bottom is fully factored, set each factor equal to zero and solve for x to find any excluded values, which are values of x that would have you dividing by zero. Use factors of the original denominator to find all of the excluded values.
