Question

How do you factor the trinomial `v^2 + 20v + 100`?

Answer 1

`(v+10)^2`

Explanation:

We must think of two numbers that have a product of 100 and a sum of 10. Thus, we can deduce that these two numbers are 10 and 10:

10+10=20
10*10=100

`(v+10)(v+10)`

Which can be summarised as:
`(v+10)^2`
