My daughter has a problem that I cannot figure out how the teacher's book came up with the answer. They did not provide the intermediate step and there are several like this. If I can see how one is worked, I can figure out the other ones.. Here is the problem....Directions: Factor each polynomial completely.
49x^2 + 28square root of 3 + 12
The answer given is (7x + 2square root of 3)^2
I can get from the answer to the problem but what comes in between!!
Thanks for your help!
