Choose the correct simplification of the expression (2x - 6)(3x2 - 3x - 6).
Are there any choices?
I would suggest to multiply each term with it's corresponding term.
So start by multiplying \[2x^2\] with everything on the right parenthesis and then multiply \[6\] with everything on the right parenthesis
Then add like terms together.
a: 6x3 - 24x2 + 6x + 12 b: 6x3 - 24x2 + 6x - 36 c: 6x3 - 24x2 + 6x + 36 d: 6x3 + 24x2 - 6x + 36
\[2x(3x^2-3x-6) + -6(3x^2-3x-6)\] Can you do that?
(2x - 6)(3x2 - 3x - 6) 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 6x^3 - 24x^2 + 6x + 36 You do a concept similar to FOILing. Just go in the same order.
