• gcd requires numeric inputs.
Factor the expression. Your answer should include only positive exponents. 1x13(2x+5)343x23(2x+5)14=\displaystyle {1}{x}^{{-\frac{{1}}{{3}}}}{\left({2}{x}+{5}\right)}^{{\frac{{3}}{{4}}}}-{3}{x}^{{\frac{{2}}{{3}}}}{\left({2}{x}+{5}\right)}^{{-\frac{{1}}{{4}}}}=  

Hint: If the leading term is negative the gcf is negative.
