Answer:
sorry I couldn't understand the language so I can't give u ans..
The factored form of the expression
is 
The expression x^2 + 9 has no real roots hence cannot be factored
Quadratic equations are equations with a degree of 2.
Given the quadratic function 
For the function 

Using the difference of two squares:

For the expression x^2 + 9
The expression x^2 + 9 has no real roots hence cannot be factored
