We start off with this expression.

This term times that term, plus this term plus this term.

This term is the same thing as this term.

This term to this term to get this term.

It really is a toss up between this term over here between this term over here and that one

And it seems like this term would overpower this term.

That term is that term right there.

This term right there is the same thing as that term right there.

I'm just literally adding this term to that term, to get that term.

And when we're adding this these parentheses aren't really doing anything cuz we're just adding this expression to that expression.

Now, if you were to undistribute 2x squared out of the expression, you'd essentially get 2x squared times this term, minus this term, minus this term.

This term is the exact same thing as this term if you just cancel the x minus 8 out, and this term is the exact same thing as this term if you just cancel the x plus 5 out.

So, so far I've taken care of that term, that term, and that term.

Now this expression is equal to this other expression.

This expression is just another way of writing this expression.

That term right there.

So I can replace this in this expression with a composition of h with f.

These two statements right here, this statement and this statement are identical.

All the way down to plus this last term times that last term.

This term multiplied by this term is just x0, and then you have a plus 1 4 x0.

This phrase will be translated.

like this expression.

This expression right here.

And let's multiply this term out.

I evaluate the expression?

What is this term?

That's that term right there.

Because this expression right over here.

So first we'll do this inner function, this inner expression.

So this term is the same thing as that term.

K plus 3 times 7k is that term, k plus 3 times negative 1 is that term.

But I hope you can see that this thing up here is the same thing is this thing right here.

So 6a squared b squared plus well 4 This term is the same as this term, right?

So 2 times b plus a has to be equal to this term is the same thing as this term right here.

This term corresponds to this one this one corresponds to this one but this term corresponds to nothing over here so you couldn't add or subtract these matrices.

And we can multiply this thing times this thing to get this term, and then this thing times that term to get that term.

We have this term has a y prime in it, we have this term has a y prime in it, and we have this term has a y prime in it.

I think that make sense if you take this entire expression and you substitute x here for this entire expression you get this expression.

Well that was not by me.

It was suggested to delete the phrase in question.

I used that phrase.

Now, this second term.

Well, that was not by me.

I love that phrase.

Americans coined that phrase.
