What is the restriction in simplifying rational algebraic expressions?
Rational expressions usually are not defined for all real numbers. The real numbers that give a value of 0 in the denominator are not part of the domain. These values are called restrictions.
What is a rational algebraic equation?
A rational equation is an equation containing at least one fraction whose numerator and denominator are polynomials, \frac{P(x)}{Q(x)}. Q(x)P(x). A common way to solve these equations is to reduce the fractions to a common denominator and then solve the equality of the numerators. ...
