1. Simplifying Rational Expressions
Sign In
Factor out 3
Cancel out common factors
Simplify quotient
a/1=a
We simplified the given expression. Finally, we will identify the restrictions on the variable from the denominator of the simplified expression and from any other denominator used. Since our final expression is not a fraction, we need to look at the expression before canceling out common factors.
Denominator | Restrictions on the Denominator | Restrictions on the Variable |
---|---|---|
x+3 | x+3≠0 | x≠- 3 |
We found one excluded value of the variable x. x≠- 3
