The second term is going to be the second something or you're going to subtract the second something squared. So you're going to have minus 3 squared, so minus 9. In the denominator you're of course going to have x minus 5 times the square root of x plus 4 plus 3. So this has, I guess you could say simplified to, although not arguably any simpler, but at least we've gotten our radical. We're really just playing around with it algebraically to see if we can then substitute x equals 5 or if we can somehow simplify it to figure out what the limit is. When you simplify the numerator up here, you get x plus 4 minus 9. Well that's x minus 5 over x minus 5 times the square root of x plus 4 plus 3.
