Use the box method to distribute and simplify (- 3x ^ 2 + 2x - 6)(- 2x - 4) .
The box is 3 rows 2 columns and make the box using these lines _
Then put the numbers where they go
Here is the simplified version of the expression using the box method:
_ -3x^2 + 2x -6
_ -2x -4
To distribute and simplify using the box method, we start by filling in the numbers in the appropriate boxes within the 3 rows and 2 columns:
_ -3x^2 + 2x -6
_ -2x -4
We then multiply each number in the first row by each number in the second row:
_ -3x^2 + 2x -6
_ -2x -4
___________________________
6x^3 - 4x^2 + 12x
-4x^2 + 2x + 8
Finally, we combine like terms by adding or subtracting the numbers in each column:
6x^3 - 8x^2 + 14x + 2
