Combine Like Terms I can simplify expressions with several variables by combining like terms.

Constant Vocabulary A number with nothing else attached to it. Examples: 1, 2, 47, 925

Variable Vocabulary A letter that represents an unknown number. Examples: a, b, x, y

Coefficient Vocabulary The number in front of the variable. Examples: 3x 3 is the coefficient 2x 2 is the coefficient

Like Terms: In an expression, like terms are the terms that have the same variables, raised to the same powers (same exponents). Examples: 4x and -3x or 2y2 and –y2

Like terms because each term consists of a single variable, x, and a numeric coefficient: 2x, 45x, x, 0x, -26x, -x Like terms because they are all constants: 15, -2, 27, 9043, 0.6 Like terms because they are all y² with a coefficient: 3y², y², -y², 26y²

What are unlike terms? The following two terms both have a single variable, but the terms are not alike since different variables are used: 17x, 17z Each y variable in the terms below has a different exponent, therefore these are unlike terms: 15y, 19y², 31y5 Although both terms below have an x variable, only one term has the y variable, thus these are not like terms either: 19x, 14xy

Combine Like Terms I can simplify expressions with several variables by combining like terms.

Like Terms – same variable with same exponent Key Skills Like Terms – same variable with same exponent Simplify When combining like terms, only use the coefficients. 6x + 2x = 6x + 2x = 8x Simplify 4x + 3y – 2x + 4y = 2x + 7y Never, NEVER, combine x’s and y’s or constant terms with variable terms. 2x + 7y ≠ 9xy and 3a + 6 ≠ 9a.
