Use FOIL to help expand the expressions

When we foil out the expression we get: 

[tex]5x*2x^2+(5x)(-3x)+(5x)(-6)+(-6)(2x^2)+(-6)(-3x)+(-6)(-6)[/tex]

Now start multiplying the expression to get: 
[tex]10x^3-15x^2-30x-12x^2+18x+36[/tex]

Combine like terms; Final answer: 
[tex]10x^3-27x^2-12x+36[/tex]

so A
