Answer:
d) 2x²(6x³ + 3x + 4) 
Step-by-step explanation:
In order to factor the given polynomial, you need to find the greatest common factor of all three terms:  
The greatest common factor is '2' and the variable is x².  If we factor out 2x² from each term, we get: 
2x²(6x³ + 3x + 4) 
 
        
             
        
        
        
25x^2+10x+1
25x^2+5x+5x+1
5x(5x+1)+1(5x+1)
(5x+1)(5x+1)
(5x+1)^2
