Answer:

[tex]6x^3-24x^2+6x+36[/tex]

Step-by-step explanation:

[tex](2x - 6)(3x^2 - 3x - 6)[/tex]

Multiply 2x-6 inside the second parenthesis

First multiply 2x inside second parenthesis'

[tex]2x(3x^2-3x-6)= 6x^3 -6x^2-12x[/tex]

[tex]-6(3x^2-3x-6)= -18x^2+18x+36[/tex]

Now we combine all the terms

[tex]6x^3 -6x^2-12x-18x^2+18x+36[/tex]

Combine like terms

[tex]6x^3-24x^2+6x+36[/tex]
