Use the box method to distribute and simplify (- 3x ^ 2 + 2x - 6)(- 2x - 4)

Question

The box is 3 rows and 2 columns and
-2x/ -4 go on the top the rest go on the left

Answer 1

Here is the box representation:

| -2x | -4 |
------------------------------------
-3x^2 | -6x^2 | -12x^2 |
------------------------------------
2x | -4x | -8x |
------------------------------------
-6 | 12 | 24 |
-------------------------------------

To distribute and simplify, we multiply the corresponding values in each box and combine like terms:

-6x^2 + 8x - 24
