Step-by-step explanation:
first do the parenthesis
4x-3(3x+3x)>18
4x-3(6x)>18
4x-18x>18
-14x>18
I'm not sure if this helps but I tried
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:
