Factorize: tan²A - tanA - 30
- There is no. 30, so we need a factor for 30.
- In middle term, there is ( tan A ), so we need those factors whose difference can be 1.
- So, there are multiple factors for 30. such as: 1,2,3,5,6,10,15 and 30.
- So, these are the factors of 30. We need the difference 1. Hence, 6 and 5 are best factors for it to make difference 1.
