If all the values of the variables in an equation are true, it is called an identity. In a conditional equation, some of the values for the variables are true, while others are false. A term is any algebraic expression consisting only of products of coefficients, constants and variables. For example, 2x, -a, and b x are terms. The coefficient is the number in front of a variable.
Polynomials are expressions with one or more terms.
A monomial has one term, while a binomial has two terms. Also, a trinomial has three terms. The degree of a polynomial is determined by calculating the highest exponent sum of the terms. This is because the sum of the exponents in the second term is higher than that of any other term. The sum of any two real numbers is a real number.
