Write the missing factor. (x + 1)( ? ) = x2 – 1

(x-1)

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have that the terms x²-1 are perfect squares:

x²-1²

2. Therefore, by definition, you have that the difference of squares formula is:

a²-b²=(a+b)(a-b)

3. Therefore, keeping the information above on mind, you have:

x²-1²=(x+1)(x-1)

Then, the missing factor is (x-1)

-1/4

Step-by-step explanation:

Use the formula: a2 divided by a1. (a2/a1)

Plugging it in would look like this:

-6/24

-6/24 is equal to -1/4.

Hope this helps!
