Question

reduce the equation to quadratic form.
2x − 2/3 + x−1/3 + 6 = 0

Answer 1

2/3+1/3 = 1
so it's
3x=-5
The rest you can do yourself.

Answer 2

these are my options

u = x−1/3
u = x1/3
u = x−2
u = x2
u = x−2/3
u = x3
u = x2/3
u = x4

Answer 3

first one works, try it and see

Answer 4

2x − 2/3 + x−1/3 + 6 = 0
is
3x+6=1
x+2-1/3=0
x=-(5/3)
Where do you get u from?

Answer 5

because i believe that the question is actually
\[2x^{ − 2/3} + x^{−1/3} + 6 = 0\]otherwise it doesn't make any sense

Answer 6

Oh
