Rational algebraic expression

• rational expression is simply a quotient of two polynomials. Or in other words, it is a fraction whose numerator and denominator are polynomials. These are examples of rational expressions: ‍ x + 5 x 2 − 4 x + 4 ‍
• The domain of the rational function is all real numbers except those that make the denominator equal to zero.
• A polynomial is an expression consisting of variables raised to non-negative integer powers and multiplied by coefficients which can be any real number or variable.
• An algebraic expression is a combination of constants, variables, and operators such as addition (+), subtraction (-), multiplication (*), division (÷).
• An algebraic expression is formed from constants, variables, and operations such as addition, subtraction, multiplication, division, exponentiation, and root extraction.
• A monomial is a single term with no grouping symbols like parentheses, brackets, or braces.
• A binomial is a polynomial with exactly two terms.
• A trinomial is an algebraic expression with three terms.
• A linear equation is a first degree polynomial equation where the highest power of the variable is 1.
• A quadratic equation is a second degree polynomial equation where the highest power of the variable is 2.
