$\sqrt[3]{(a+1)^{2} (a^{2}+2a-1 )-(a-1)^{2}(a^{2}-2a-1 ) }\\\\ \sqrt[3]{(a^{2}+2a +1) (a^{2}+2a-1 )-(a^{2} -2a+1)(a^{2}-2a-1 ) }\\\\ \sqrt[3]{(a^{2}+2a)^{2}-1^{2} -((a^{2} -2a)^{2} -1^{2} )}\\\\ \sqrt[3]{(a^{2}+2a)^{2}-1 -((a^{2} -2a)^{2} -1 )}\\\\ \sqrt[3]{(a^{2}+2a)^{2}-1 -(a^{2} -2a)^{2} +1 }\\\\ \sqrt[3]{(a^{2}+2a)^{2}-(a^{2} -2a)^{2}}\\\\ \sqrt[3]{(a^{2}+2a-(a^{2}-2a ))(a^{2} +2a+a^{2} -2a)}\\\\ \sqrt[3]{(a^{2}+2a-a^{2}+2a )(a^{2} +a^{2} )}\\\\\sqrt[3]{(2a+2a )(2a^{2} )}$

$\sqrt[3]{(4a)(2a^{2} )}\\\\\sqrt[3]{(8a^{3} )}\\\\2a$
