Question

Find the product 3(x + 4 )( x - 5)​

Answer 1

3x + 3x4 ( x - 5 )
= 3x + 12 ( x - 5 )
= 3x^2 - 15x + 12x - 60
= 3x^2 - 3x - 60

Answer 2

`3x^2-3x-60`

Explanation:

Given:
`3(x+4)(x-5)`

Let's use the distributive property to multiply
`(x+4)(x-5)` together since they are right next to each other. We can use the FOIL method.

`(x+4)(x-5)\\x^2-5x+4x-20\\x^2-x-20`

Now that we simplified that, we still have to multiply everything by the value of
`3.`

`3(x^2-x-20)\\3x^2-3x-60`

Now, you could have left the answer as
`3(x^2-x-20)` since it is factored, but the problem wants us to find the product, so we need to completely simplify.
