find the real solutions of 6x^(2/3) - 11x^(1/3) - 2 = 0

[almostbrain]

6x^(2/3) - 11x^(1/3) - 2 = 0

No idea here, except to do this 6x^(2/3)*(3/2)....well maybe do that

Have you considered the quadratic formula? x^(1/3) = (-b +/- stuff)/(2a)?

No idea here

So your class has not covered how to solve quadratic equations...?

quadratic

my class hasn't taught me nething...i don't have a teacher---the class got books, thats what we have to go on

but i'll give it a shot with this problem

Re: quadratic

[M]y class hasn't taught me [any]thing.

So you're needing lessons on how to solve quadratics first, because this exercise assumes that this topic has already been covered in class. The following lessons should serve to get you started.

. . . . .Factoring Quadratics

. . . . .The Quadratic Formula

. . . . .Solving Quadratic Equations

Give yourself a day or two to absorb the content, and then attempt the exercise again, noting that x^2/3 = (x^1/3)².

You might also want to have a serious talk with your academic counsellor regarding placement, or an administrator regarding the lack of instruction taking place.


Good luck!
