To take the square root of a number, you need to answer the question: What other number when multiplied by itself gives you the original number.

So what number multiplied by itself gives you ? Well, we know that , so there is part of the answer to that part, namely: . You also have to consider that also. So OR .

Apply this same logic to the number 16. What number, multiplied by itself, makes 16? Remember that and .

So now we have: or (You can also say or , but those are just equivalent expressions to the ones already given.)

Do the other problem the same way. You'll get equal to plus or minus something, so you will need to solve each of those resulting equations by adding 3 to both sides.
