If you would like to solve (2x - 6) * (3x^2 - 3x - 6), you can do this using the following steps:
(2x - 6) * (3x^2 - 3x - 6<span>) = 2x * 3x^2 - 2x * 3x - 2x * 6 - 6 * 3x^2 + 6 * 3x + 6 * 6 = 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 = 6x^3 - 24x^2 + 6x + 36
</span>
The correct result would be <span>6x^3 - 24x^2 + 6x + 36.</span>
(4,7) because 3•4 = 12 and 12+7 = 19

In this case we have the following expression:

We know that Karen was trying to factor out this and she found that the greatest common factor of these terms was 2, in other words we can write this expression as:

An area model for this expression could be the area of a rectangle that has the following dimensions:

So the area model can be written as:

Divide the 10 by 4, which makes the x be 2.5. You can check it by multiplying 4 by 2.5, which will give you 10.
