For this case we have the following steps:
Step 1:
We apply distributive property, which states:
[tex]a (b + c) = ab + ac[/tex]
Applying the property to the product of "3" and the first parenthesis we have:
[tex](3x + 12) (x-5)[/tex]
Step 2:
Apply distributive property again
[tex]3x ^ 2-15x + 12x-60[/tex]
Step 3:
We add similar terms
[tex]3x ^ 2-3x-60[/tex]
Thus, the product is given by: [tex]3x ^ 2-3x-60[/tex]
Answer:
[tex]3x ^ 2-3x-60[/tex]
