Question

Choose the correct simplification of (5x − 6)(2x2 − 3x − 6).

Answer 1

$(5x - 6)(2x^2 -3x - 6)$

Use FOIL to help expand the expressions

First
Outer
Inner
Last

When we foil out the expression we get: 

$5x*2x^2+(5x)(-3x)+(5x)(-6)+(-6)(2x^2)+(-6)(-3x)+(-6)(-6)$

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

Combine like terms; Final answer: 
$10x^3-27x^2-12x+36$

so A
