I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a
        
             
        
        
        
Answer:
when a expression is squared (²) that means it is multiplyed by itself.
Step-by-step explanation:
(1/2)² = (1/2 x 1/2) 
1 squared = 1
2 squared = 4
1/4 is smaller than 1/2. 1/2 is greater than (1/2)²
