Hi guys! This video discusses the definition and simplification of rational algebraic expressions. Basically, rational expressions are fractions whose numerators and denominators are algebraic expressions mostly polynomials. Being a fraction, the restriction is that we would not allow values for the variable, say x, that will make the denominator zero. By simplification of rational expressions, we mean we cancel out the common factors in the numerator and denominator after we factor out the polynomials. We illustrate examples on simplification rational expressions. Happy learning and enjoy watching! #math #tagalog #algebra
