Podeli obe strane jednačine sa [inlmath]\sqrt[3]{\left(2-x\right)^2}[/inlmath], a zatim uvedi smenu [inlmath]\sqrt[3]{\frac{2+x}{2-x}}=t[/inlmath].
Drugi način, vrlo sličan, jeste da obe strane jednačine podeliš sa [inlmath]\sqrt[3]{\left(2+x\right)^2}[/inlmath], a zatim uvedeš smenu [inlmath]\sqrt[3]{\frac{2-x}{2+x}}=t[/inlmath].
