Minus y to the fourth over did I mess up some place?

We can actually simplify it because 9, 3, and minus 18 are all divisible by 3.

So they write, x squared plus 8x plus 16, over x plus 3, divided by 2x plus 8, over x squared minus 9.

So let's divide the numerator and the denominator by 5 and see what we get.

So to go from a to the minus one to a to the minus two,

So let's divide both the numerator and the denominator by 7.

And I got that, in every case, by just dividing these guys all by twenty.

180 plus 36 is 216.

So let's see.

We'll reimburse you ... in installments

To isolate the x, we can just divide both sides of this equation by 3.

So let's divide both the top number and the bottom number by 4.

So 27 divided by negative 12, well, they're both divisible by 3.

5 over 35 I'm leaving some space so we can divide well, these are both divisible by 5, so let's divide the numerator and the denominator by 5.

So if we go from a to the first, which is just a, and divide by a, right, so we're just going to go we're just going to divide it by a.

Or we could say, look, this is going to be equal to 48 times 5, whatever that is, over 4.

Both the numerator and the denominator are divisible by 3.

In return on equity, the numerator is the net income that we got, so it's 350,000.

So divide the numerator by 3, and let's divide the denominator by 3.

This one over here we added up all the digits and got 18, 18 is divisible by 9.

If we do the same thing to numerator and denominator we're not going to be changing the value of fraction.

So let's say you did it with 4.

Now, this numerator up here, we can factor it.

Plus 1 is 33. 62 00 03 16,95 gt 00 03 20,75 And now we divide this number by 4.

Well, 4 times 84, we already said, is 336.

Well, they definitely have a common factor, you have a negative 3 or positive 3 common to both of these.

Well y was equal to p times x so y divided by x is gonna be the same as p times x divided by x

You immediately see 6 and 4 are both divisible by 2, so let's divide them both by 2.

So here we're divisible by 2 and 3, so we're going to be divisible by 6.

Then to discount money in the future to the present, we divide it by 1 plus the discount rate so this is a 5 discount rate.

And then it would have been more obvious that you can divide the numerator and the denominator by 2 once you can do it again and then you'd just be left with one over two times 5 times 5.

They're both divisible by 2, so if we want it in lowest terms, we want to divide them both by 2.

Times C, which is 9.

Add 13 to both sides and we get 8r these guys cancel out is less than 23, and then we divide both sides by 8.

Now I wanna divide both sides of this equation by negative 13.

But if we divide over here both sides by 3, what do we get?

We divide the left by 3.

So 110 in 2 years, what is its 1 year value?

I divide by 1.05, and then I divide by 1.05 again.

And so we want to figure out what r is.

That does simplify a little bit.

How could we get this equation into this form?

We are left with an x plus 4 times an x minus 3.

So m times V squared is equal to 2 times the work.

You see where this is going.
