Accepted Answer

Hello Today we're going to be rewriting this complex expression in standard form. So the expression given to us is I plus one minus the quantity I minus one. Now, in order to start simplifying this, we're going to need to open up these parentheses and in order to do that we're going to need to distribute negative one to the quantity I -1. Doing so is going to give us the expression I plus 1 -1. Now we need to go ahead and combine the like terms while I minus I is just going to cancel each other out and what we are left with is one plus one which is equal to two. And this is going to be the simplified version of our given expression. And that also means that the answer to this problem is going to be seen. So I hope this video helps you in understanding how to simplify this given expression and I'll go ahead and see you all in the next video.
