5v^2+50v+80=5(v+2)(v+8)
Explanation:
- All of the numbers given can be divided by 5, so the first step is to factor out the 5:
5(v^2+10v+16)
- Now we need to find two numbers that when multiplied = 16 and when added together = 10. The numbers that fit this are 2 and 8 and so the final answer becomes:
5(v+2)(v+8)
