So you have:
25v² + 5v² + 30v + 6
First you combine the like terms (all of the v²)
25v² + 5v² + 30v + 6
= 30v² + 30v + 6 (25v² + 5v² = 30v²)
Now notice that the largest common factor of all those numbers is 6. So you can take out a factor of 6:
30v² + 30v + 6
= 6 (5v² + 5v + 1)

Answer:
25v² + 5v² + 30v + 6
= 30v² + 30v + 6
= 6 (5v² + 5v + 1)
