Answer:
Step-by-step explanation:
Factor each expression
product =9 and sum =6
3 times 3 is 9
3 plus 3 is 6
2. Factor completely: 5x^2 − 5
GCF is 5
3. Factor completely: 3t^3 + 18t^2 − 48t
product is -16 and sum is 6
-2 times 8 = -16
-2+8=6
4. Factor completely: 4n − n^3
The expression that is not a rational expression is:
A rational expression is an expression that has a variable in the denominator.
For expression , x + 3 is a common term to the numerator and denominator, hence it is simplified to 2x - 1 and is not a rational expression.
