The expression is ambiguous. Please include grouping symbols as necessary to make the expression unmistakeable to read. Do you actually have THIS expression?

%28%281%2F5%29+x+%2B+1%2F3%29+%28%281%2F5%29+x+-+1%2F3%29
?

If this is the case, you may recognize the formula for Difference Of Squares.
(Example, %28a%2Bb%29%28a-b%29=a%5E2-b%5E2 ).
