6. Find the product:

(x² + 8x - 3) (x + 1)

x^3+9x^2-3x^2-3

Step-by-step explanation:

You can use a various of methods but when you use the box method you multiply each separately.

Like you would multiply x² by x, 8x by x, - 3 by x (thats the first row)

x² by 1, 8x by 1, - 3 by 1 (for the second row)

Then you get those final variables and combine like terms getting the answer above
