Question 38242: Find the following product and express answer in simplest radical form. All variables represent non negative real numbers.
((SQRT of 17a) + (SQRT of 7y))((SQRT of 17a)-(SQRT of 7y))

The problem [sqrt(17a) + sqrt(7y)] * [sqrt(17a) - sqrt(7y)] is merely a complicated sum times a difference problem...which is of the form
(a+b)(a-b) = a^2 - b^2
Same thing here...
[sqrt(17a) + sqrt(7y)] * [sqrt(17a) - sqrt(7y)] =
17a - 7y
