Answer:
(3x^2 - 2x + 5)
Step-by-step explanation:
 3x^2 - 2x + 5

 
 - <u>(6x^3 + 3x^2)</u>
 -4x^2 +8x +5
 - <u>(-4x^2 - 2x)</u>
 10x + 5
 -(<u>10x + 5)</u>
 00
(2x+1) (3x^2 - 2x + 5) = 6x^3 - x^2 + 8x + 5
Therefore the other factor of the polynomial is (3x^2 - 2x + 5)
 
        
                    
             
        
        
        
N / 2
400 / 2 = 200
200 / 2 = 100
100 / 2 = 50
50 / 2 = 25
25 / 2 = 12.5
