You can put this solution on YOUR website!
Multiply:
%28x-1%2F3%29%28x%2B1%2F3%29
There is a couple of ways the answer might look:
You can notice that these are conjugates and thus result in the difference of perfect squares:
highlight%28x%5E2-1%2F9%29
Or if you give the terms a common denominator:
%28x-1%2F3%29%28x%2B1%2F3%29
%283x%2F3-1%2F3%29%283x%2F3%2B1%2F3%29
%28%283x-1%29%2F3%29%28%283x%2B1%29%2F3%29
highlight%28%289x%5E2-1%29%2F9%29
Happy Calculating!!!!
