Question

How do you factor `w^2+4w+3`?

Answer 1

`(w+3)(w+1)`

Explanation:

In this case, since `a = 1` (in `ax^2+bx+c`), simply look for two numbers whose sum is `4` and whose product is `3`. You can easily see that the two numbers are `1` and `3`.

Then, just write it down: `(w+3)(w+1)`

Check: try expanding the brackets using FOIL.
