If we square both sides we get x^4 + 4x^3 + 4x^2 = 9x^2
welshfella
  • welshfella
x^4 + 4x^3 - 5x^2 = 0 x^2(x^2 + 4x - 5) = 0 x^2(x + 5)(x - 1) = 0 x = 0, 1 , -5

but is it ok to square nd simplify like that when u have greatest integer function there?
welshfella
  • welshfella
to be honest i'm not sure 1 would be greatest integer function i guess
welshfella
  • welshfella
I'll check it out
ytrewqmiswi
  • ytrewqmiswi
ok
welshfella
  • welshfella
[0,2] must be the domain so the greatest integer function would be 1

-5 is an extraneous solution
