Example Question #1 : Rational Expressions
Rationalize the following fraction:
Rationalize the following fraction:
To rationalize a denominator, we will multiply the top and bottom of the fraction by the denominator.
And we have our answer
Example Question #2 : Rational Expressions
Simplify the following:
First we need to factor both polynomials.
Becomes
Now we cancel out any variables that are in BOTH the numerator and denominator. Remember that if a group of variables/numbers are inside parenthesis, they are considered a single term.
The common term in this case is , removing that from the equation gives us
Example Question #2 : Rational Expressions
Simplify the following
The first step is to factor both polynomials:
Becomes
Now we cancel out any terms that are in both the numerator and denominator. Remember that any variables/numbers that are in parenthesis are considered a single term.
In this case, the common term is
Once we remove that, we are left with:
