Answer:


(4x+5)(x-3)

Explanation:

We can separate this expression into two parts:
4x^2-12x and
5x-15.

We can first take the first part and factor out 4x, getting
4x(x-3).

We can then take the second part and factor out 5, getting
5(x-3).

Now when we put these parts together, they make
4x(x-3)+5(x-3)\\.

The last step is to factor
(x-3) to get
(4x+5)(x-3).
