so it's like 'which one of the number given is a factor of, say, 10' and the choices are 4,5,7,9. the answer is 5 so just factor out the equation
the factored out form is factor out the 3x^2 and get (3x^2)(3x^2-2x+1) and 3x^2-2x+1 is the fourth choice
The factorization of the expression 9 x 4 − 6 x 3 + 3 x 2 reveals that a valid factor is 3 x 2 − 2 x + 1 . This is derived by factoring out the greatest common factor, which is 3 x 2 . Hence, the correct choice is Option D.
