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

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

So a squared plus b squared is equal to c squared.

So by the Pythagorean theorem, 9 squared plus 7 squared is going to be equal to c squared.

A squared plus the opposite squared.

So we have a 4x squared, we have a minus x squared.

This is a squared minus b squared.

And then when you add p squared to negative 2p squared you're left with negative p squared minus p squared.

Now we can square both sides of this equation. It's not the cleanest problem in the world, but hopefully, if we haven't made any mistakes, we'll get someplace productive. Actually, let's multiply both sides of this equation times negative 1 just to make it positive and simplify things.

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

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

What if I had x squared plus y squared is equal to 100.

So 3 squared is equal to r squared.

9 squared is 81, plus 7 squared is 49.

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

And then we have p squared minus 2p squared.

Alright, that's 13 squared plus sin9 squared.

6 times x squared is 6x squared.

And a squared divided by a squared is just a.

And 4a squared times minus 5 is minus 20a squared.

This has x plus 1 squared minus y squared.

And that makes sense because a plus b squared is 1a squared plus 2ab plus 1b squared.

3 plus A. 3x squared plus Ax squared, that's the same thing as 3 plus A, x squared.

I'm getting a little misaligned 3y squared times negative 1 squared.

Well it's just x squared over 2.

And so this definitely is equal to a squared minus b squared.

2x squared.

It says the point minus 3, 2 lies on a circle whose equation is x plus 3 squared plus y plus 1 squared is equal to r squared.

So now we have s squared plus a squared, over s squared, times y is equal to this.

And this is the correct answer. a over s squared plus a squared.

So the area of this parallelogram right over here is going to be a squared.

Wrong, wrong, wrong.

We can rearrange this as 3x squared plus Ax squared minus 2x plus Bx is equal to 5x squared minus 6x.

So 2a times c squared is 2ac squared.

Is equal to 13 squared.

Which is just equal to x squared.

Plus 3 squared.

Take the square of that.

So 2x squared.

But what's the derivative of x squared what's the derivative x squared plus 1?

The Pythagorean theorem tells us that if and only if this is a right triangle, then a squared plus b squared is going to be equal to c squared.

So this entire area of this entire square is still a squared plus b squared. a squared is this entire area right over here.

Of x squared, plus the derivative with respect to x of y squared.

We went from 5 m (s 2) to 10 m (s 2)

And then we can simplify this even more because both the numerator and the denominator is divisible by x squared. x squared divided by x squared is 1. x to the third divided by x squared is just going to be equal to x.
