Rational Expressions and Operations

• k = 7
• x = 7.1
• x = 7.6
• x = 1/7

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.
