Operations with Rational Expressions

When adding and subtracting rational expressions, my first step should be to:

• Combine like terms in the numerators.
• Determine a Least Common Denominator.
• Factor all of the numerators and all of the denominators.
• Change the operator to multiplication and reciprocate the second fraction.

My first step will be to change the operator to multiplication and flip the second fraction when...

• Adding
• Subtracting
• Multiplying
• Dividing

To simplify a rational expression, I should

• Eliminate common terms in the numerator and denominator.
• Combine like terms in the numerator and denominator.
• Factor the numerator and denominator and eliminate common factors.
• Find an LCD.
