Using the distributive law of multiplication over subtraction i have a question
Why is the answer not ?
Because in the first half of the answer the x is under the radicand. While in the second half the x is outside the radicand. I do not understand why one x would be included under the radicand while the other would not.
Please Help Clarify & Many Thanks
That is the answer. The order of the variables in each term shouldn't change the answer; however, when we have expressions where there are terms that contain x and y, we usually write x first, and then y.
is correct, but so is this
Well, in the second term, the x term is inside and outside the radical.Because in the first half of the answer the x is under the radicand. While in the second half the x is outside the radicand. I do not understand why one x would be included under the radicand while the other would not.

We could, however, combine and , but I believe that is beyond what the question is asking.
Does this help?

Not it does not ask me to, but im curious as to how to simply this. Im guessing its Using . But im not sure how it works out with another x right beside it.
EDIT: And yes it does help chris, but i would like to go beyond what the question is asking to enhance my knowledge.
