Algebra Terms In an algebraic expression such as 2 3 + x , x 3 and 2 are called terms of the expression. x 3 is a variable term and 2 is a constant . In the term x 3 , 3 is called the coefficient and x is called the variable . Like terms have the same variables and exponents. They can be combined by addition or subtraction. y 2 and y 8 are like terms. ( 29 y y y 10 8 2 = + 2 2 x and 2 5 x are like terms. ( 29 2 2 2 3 5 2 x x x - = - Unlike terms have different variables or different exponents and cannot be combined by addition or subtraction. x 3 and y 7 are unlike terms. 2 2 x and x

Unformatted text preview: 6 are unlike terms. • Algebraic expressions are also called polynomials. Polynomials are expressions in which terms are added or subtracted. • Simple polynomials have special names based on the number of terms found in the polynomial Name Number of Terms Example Monomial 1 4 3 x Binomial 2 y x 5 3 4 + Trinomial 3 7 6 2 2 +-x x • Polynomials can be added or subtracted. This is done by adding or subtracting like terms. Combining like terms is called simplifying....
