The answer is: " (y + 3) (y + 2) " .
__________________________________________________
Or, write as: " (y + 2) (y + 3) " .
__________________________________________________
Given: " y² + 5y + 6 " ;
__________________________________________________
we see that:
___________________
we have +5y and +6 ;
___________________
so, the factors 6 that would add up to "5" would be:
___________________________________________
1, 6 = 7 ; no.
2, 3 = 5 ; yes!
3, 2 = 5 ; yes! (same as above).
6, 1 = 7 ; no (same as above).
___________________________________________
So, we have: (y + 3) (y + 2) = y² + 5y + 6 ;
Or ; (y + 2) (y + 3) = y² + 5y + 6 .
