❓ Frequently Asked Questions
What is an algebraic fraction?
A fraction whose numerator and/or denominator are algebraic expressions (for example polynomials). The value is defined for all x that do not make the denominator zero.
How do you simplify an algebraic fraction?
Factor the numerator and denominator, cancel any common factors, and remember the domain restriction: x cannot make the denominator zero.
How do you add or subtract algebraic fractions?
Factor the denominators, find a common denominator, rewrite each fraction with that denominator, combine the numerators, then simplify and exclude any invalid x-values.
How do you multiply or divide algebraic fractions?
Multiply the numerators together and the denominators together. To divide, multiply by the reciprocal. Cancel common factors before multiplying to simplify.
What about complex fractions?
A fraction within a fraction. Clear the inner fractions by multiplying top and bottom by a suitable value (or rewrite using reciprocals) to obtain a single fraction.
