@ reiny. . . 9x^4-24x^3+16x^2. .i have done it bt i want you to do it 4 me to confirm
yes, I saw your reply, I messed up at the last step
...
x^2(9x^2 - 24x + 16) = 0
x^2(3x - 4)^2 = 0
x^2 = 0 or 3x-4 = 0
x = 0 or x = 4/3
...
x^2(9x^2 - 24x + 16) = 0
x^2(3x - 4)^2 = 0
x^2 = 0 or 3x-4 = 0
x = 0 or x = 4/3
