How do you simplify and find the excluded value of #(3x^2 - 3) /( 6x - 6 )#?
excluded value is x = 1 for unsimplified expression
no excluded value for simplified expression
to find excluded value set denominator = 0 and solve for variable to find excluded value. Since cannot divide by 0, any value of the variable that makes the denominator = 0 is excluded
