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.

• 10 / 14a⁴

• 21 / 49a⁴

• 3 / a⁴

• 3 / 7a⁴

• 7(r + 2)/ (r + 2)

• (r - 8) / (r + 2)
