Question

How do you factor `10x +15`?

Answer 1

`5(2x+3)`

Explanation:

To factor this, we first have to find the factors that both numbers have in common. Let's list out the factors of each number:
`10: 1, 2, 5, 10`

`15: 1, 3, 5, 15`

Now we need to find the largest factor that both have in common. That number is `5`.

If you divide `10` by that number, you get `2`.

If you divide `15` by that number, you get `3`.

So the factored form becomes:
`5(2x+3)`

Hope this helps!
