Question

9x^4-21x^2+10=0
solve!

Answer 1

(3x^2-2)(3x^2-5)
x= sqrt (2/3) x=sqrt (5/3)

Answer 2

wrong!!

Answer 3

factors are needed.

Answer 4

so how would i write it?

Answer 5

9x^4-15x^2-6x^2+10 = 0
3x^2(3x^2-5)-2(3x^2-5) = 0
(3x^2-5)(3x^2-2) = 0

x = +/- sqrt{5/3}
x = +/-sqrt{2/3}

Answer 6

Still NO.

Answer 7

Well Legend....Since you seem to know the solution, why don't you reveal it oh great one...

Answer 8

Well Zero, factors are needed. I know

Okay. I guess you must be taking the same online test she is. Either way, you can't say it's wrong if we correctly posted the solution for the question she did write. Go away Absolute Zero.

Answer 21

I never said that solutions are wrong.
Solutions are right, but the answers in which form they are needed, they are incorrect.

Answer 22

Let me guess....another U of P online tester....

Answer 23

U of P obviously got their math program from the Illuminati wing of the Mafia.
