No.

You are left with .....(I)

So ...(II)

if you compare I and II, you should see that c = 8.

So you need to have , which is equal to

now if you look at equation (I) again, you already have .

To make this ,

you need to add 58 right?

so,

Now put the above equation in the form of - May 20th 2010, 08:55 AMtysonrss
