Answer:

[tex](4x+5)(x-3)[/tex]

Step-by-step explanation:

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

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

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

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

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