Question

Find the product of 3(x+4)(x-5)

Answer 1

First distribute the 3
(3x + 12)(x - 5)
Multiply
3x${^2}$ - 3x - 60

Answer 2

For this case we have the following steps:

Step 1:

We apply distributive property, which states:

$a (b + c) = ab + ac$

Applying the property to the product of "3" and the first parenthesis we have:

$(3x + 12) (x-5)$

Step 2:

Apply distributive property again

$3x ^ 2-15x + 12x-60$

Step 3:

We add similar terms

$3x ^ 2-3x-60$

Thus, the product is given by: $3x ^ 2-3x-60$

Answer:

$3x ^ 2-3x-60$
