# Algebraic Expressions Practice Test Questions Answers

Algebraic Expressions Practice Test Questions Answers: An algebraic expression is formed from variables and constants using different operations. Expressions are made up of terms. A term is the product of factors. Factors may be numerical as well as algebraic (literal). The coefficient is the numerical factor in a term. Sometimes, any factor in a term is called the coefficient of the remaining part of the term.

In general, an expression with one or more than one term (with nonnegative integral exponents of the variables) is called a ‘Polynomial’. To find the value of an expression, we substitute the values of the variables in the expression and then simplify.
