Question

How do you factor the trinomial `x^2- 3x + 2`?

Answer 1

Find a pair of numbers that add up to `-3` and has `2` as a product.

Explanation:

Factoring `2` will give two possibilities:
`2=1*2=(-1).(-2)`

You will find that only `-1and-2` will add up to `-3`

Now the factoring goes like:
`=(x-1)(x-2)`
