To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.


Example of Evaluating an Algebraic Expression

  • To evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add.

    4.5 + x = 4.5 + 3.2


Solved Example on Evaluating an Algebraic Expression

Evaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.


A. 12

B. 18

C. 3

D. 6

Correct Answer: D


Step 1: p + 3q + 2p - 3q [Original expression.]

Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]

Step 3: = 3p [Solve within the grouping symbols.]

Step 4: = 3 x 2 [Substitute 2 for p.]

Step 5: = 6 [Multiply.]

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials
