all right let's look at the homework 1.5 problem number six all right so let's evaluate this limit here all right so first thing you should do is plug in a number see what happens all right so if you plug in 14 here so you have a 14 plus 2 that's 16 square root of 16 is 4 4 minus 4 is 0 so you can see that the numerator approaches 0 all right then denominator 14-14 denominator also approaches 0 all right so we have to do a little bit more work all right so the trick was we're going to try to multiply top and bottom by square root of x plus 2 plus 4 right so difference is this is a minus sign here so you have a plus sign and that we're gonna have to do the same thing to the denominator so that we don't change the quantity right then this is going to be equal to all right so we still have to evaluate the limit as X approaches 14 all right the numerator since you have a minus B times quant
