[tex](2x-6)(3x^2-3x-6)[/tex]
To simplify the given expression:
1. Remove parenthesis. Distributive properti.
[tex](a+b)(c+d+e)=ac+ad+ae+bc+bd+be[/tex][tex]=6x^3-6x^2-12x-18x^2+18x+36[/tex]
2. Combine like terms
"Like terms" are terms whose variables (and their exponents) are the same
[tex]=6x^3-24x^2+6x+36[/tex]
