So these brackets are here,

Simplify negative one times this expression in brackets negative seven plus 2 times 3 plus 2 minus 5 in parentheses, squared.

Open, close, square brackets comma 1.

Well you printed out the brackets and then replaced the old brackets with the new ones.

Sometimes they're written with brackets around them.

It's equal to a squared b squared, plus a squared d squared, plus c squared b squared, plus c squared d squared, minus a squared b squared, minus 2abcd, minus c squared, d squared.

Our area squared is equal to a squared times b squared. a squared times d squared, plus c squared times b squared, plus c squared times d squared.

brackets are really just parentheses that look a

Multiply both sides by b squared. y squared is equal to b squared over a squared x squared plus b squared.

You could maybe represent it with brackets like that.

And I tend to put brackets around my matrices.

I don't know why I put brackets around that.

So 4x squared minus x squared is 3x squared.

3v squared minus 2v squared is just v squared.

9 squared is 3x squared.

4x squared is 2x squared.

So what's threei squared? threei squared is equal to three squared times i squared.

60 squared plus 32 squared is equal to x squared.

2x squared is 4x squared, and 1 squared is 1.

Z squared minus 4, that's a squared minus b squared.

And that equals c squared minus d squared i squared.

You don't have to worry about adding brackets and things.

And the way to do that is through these brackets.

Detach the panel from its mounting brackets, just as before

It's a squared minus b squared.

Of a squared plus b squared.

A squared minus b squared, right?

Minus 11x squared minus 11x squared.

This squared plus this squared is going to equal that squared.

It's s over s squared over s squared plus a squared.

So minus 7x squared minus 4x squared is minus 11x squared.

So a squared is equal to x squared minus 2xf plus f squared plus y squared.

So then you get b squared over a squared x squared is equal to b squared.

You add a squared to both sides, and you get f squared is equal to b squared plus a squared or a squared plus b squared.

It's 1 over s squared. y is equal to 1 over s squared, times s squared, over s squared plus a squared.

But that's the same thing as s squared over s squared, plus a squared over s squared.

So it's x squared over a squared plus y squared over b squared is equal to 1.

So now, the plus, the star, the question mark, the open square brackets, the closed square brackets they all mean something special in regular expressions.

This becomes f squared over a squared minus 1 times x squared.

And the denominator becomes a squared times f squared minus a squared.

Multiply both sides times s squared over s squared plus a squared.

I just factor out the x squared there, minus y squared is equal to f squared, the focal length squared, minus a squared.

That equals a squared minus b squared.
