Question

How do you simplify `(2x + 1)(x + 3)`?

Answer 1

the answer is `2x^2+7x+3`

Explanation:

just multiply them by each other. so `2x to x and 2x to 3` and make sure you get all the numbers. now do the same for the second number. you'll get `2x^2+6x+x+3` don't factor b/c it's already in factored form, you want the whole equation. so you add like terms and the only one you can add is `6x+x` so then you get `2x^2+7x+3`
