Adding and Subtracting Algebraic Expressions Objective: Students will add and subtract algebraic expressions. Recall that only like terms can be added or subtracted. Simplify the following problem by combining like terms. Ex 1: (2n + 3) + (4n + 5) Ex 2: (-3h + 2) + 3(4h - 2) ***Subtraction of expressions can be especially difficult!

Quadnomial: A quadnomial is an expression with four terms. Examples of quadnomial are: x3 + 3x2 + 10x + 7 and x3 + 3x2 + 5x2 + 10x + 7. Step 6 Since, the expression 3 + 2x3 + 3x2 + 7x2 can be simplified as 2x3 + 10x2 + 3 and has 3 different terms such as 2x3, 10x2, 3, the expression is Trinomial . Step 7 Thus, option b is the correct answer.

The above expressions were obtained by combining variables with constants. We can also obtain expressions by combining variables with themselves or with other variables. Look at how the following expressions are obtained: x2, 2y2, 3x2 –5, xy, 4xy + 7 (i) The expression x2 is obtained by multiplying the variable x by itself; x × x = x2
