(X^2)(3X-4)(3X-4)
EDIT : Instructions
Factor out (X^2), then factor 9X^2-24X+16

you probably could do this if you made a decent effort and i guess you're just a lazy cunt but here it is anyway
9x^4 - 24x^3 + 16x^2 = 0
x^2(9x^2 - 24x + 16) = 0
(a + b)^2 = a^2 + 2ab + b^2 so it's pretty clear that 9x^2 - 24x + 16 = (3x - 4)^2
x^2(3x - 4)^2 = 0
Any number multiplied by itself is 0, so either x^2 is 0 or 3x - 4 = 0.
So our solutions are x = 0 and x = 4/3

9x^4-24x^3+16x^2=0 x^2(9x^2-24x+16)=0 First, x^2=0 and 9x^2-24x+16=0. Solve those first. The only number multiplied by itself and equals 0 is 0. so one answer is 0. then you would factor the other piece. (3x-4)(3x-4)=0 What number for either x would make it equal 0? 4/3 So the answers are 0 and 4/3
