(-1-7f)to the power of 2
please explain

The product to this problem is simplified to:  

Step-by-step explanation:

1) First place out what was given:

Squared is the same thing as multiply to itself, so you would create a pair of

 

(For example, if you said: it is the same as saying or putting: x · x)

2) Then create your pair which would look like:

3) Next step is to do the FOIL method

(The FOIL method is where you do First, Outside, Inside, an Last)

(Like how it is shown in the picture, we will do this method and create one whole expression!)

4) Creating and combining your expression into one whole problem, by using the foil method.

First - F:

Outside - O:

Inside - I:

Last:

This will be:

And this will be your answer!
