4. HOW TO SIMPLIFY RATIONAL ALGEBRAIC EXPRESSION In simplifying Rational Algebraic Expression. There are three steps that we need to consider.   Factor completely the numerator and denominator. Separate and divide out common factor/s if there is/are any. Multiply the remaining factors.

5. EXAMPLE 1 Write the rational expression in simplest form . S tep 1. = ( Factor completely the numerator and denominator ) Step 2. Separate from to get Step 3 Simplify the equation and we will get 1 =  

6. Example 2 Write the rational expression in in simplest form . Step 1. = x Step 2. x = x1 Step 3. W e multiply the remaining factors x1 to get the final answer . =
