Answer ↓


\boxed{x^2-1} is the ans

Calculations ↓

First, multiply x times x :

Now multiply x times (-1) :

-1x or -x

Right now we have

x²-x

Now multiply 1 times x :

x

x²-x+x

Now multiply -1 times 1 :

-1

x^2+x-x-1

the x's cancel :

x^2-1

So the simplified expression is :


\blue{\boxed{\pmb{x^2-1}}
