To simplify the expression using the box method, we can create a box with two columns and two rows.
First, list the terms horizontally at the top of the box:
-6x -5
----------
-x^2
-x
Next, fill in the boxes by multiplying the terms in each row and column:
-6x -5
-------------------
-x^2 |-6x^3 -5x^2
-x | 6x^2 5x
Now, add the terms in each box:
-6x^3 + (-5x^2) + 6x^2 + 5x
Combine like terms to simplify:
-6x^3 +6x^2 -5x^2 + 5x
-6x^3 + x^2 +5x
Thus, the simplified expression is -6x^3 + x^2 +5x.
(−x^2 −x)(−6x−5)
Use the box method to distribute and simplify
