Rational Expressions – Restrictions When working with rational expressions, we must remember that it is not possible to divide by zero. So we will identify / define values that are “NON-PERMISSIBLE “. Steps : 1. Factor completely ( if needed ) 2. Set your denominator = 0 and solve for your variable
