Answer
DOES NOT MAKE SENSE.
The standard form of a quadratic equation is $ax^2 + bx + c = 0$
$5x^{\frac{2}{3}}+ 11x^{\frac{1}{3}}+ 2 = 0$ can be rewritten as:
$5x^2+11x+2=0$ by letting $u=x^{\frac{1}{3}}$.
Likewise, $11x^{\frac{1}{3}} +5x^{\frac{2}{3}}+ 2 = 0$ can be rewritten as:
$11x+5x^2 +2=0$ by letting $u=x^{\frac{1}{3}}$.
Both equations are still in quadratic form.
