Key Concepts

Rational Expressions

A rational expression is a fraction where both the numerator and the denominator are polynomials. The key focus is identifying the values for which the expression is defined, specifically avoiding division by zero.

Domain Restrictions

Domain restrictions refer to the limitations on the possible values of a variable in an expression, particularly those values that result in an undefined operation like division by zero. Finding these restrictions typically involves setting the denominator equal to zero and solving for the variable.
