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....
