Which of the following is a factor of 32x3 + 4?

2x – 1

4x2 – 4x + 1

4x2 – 2x + 1

None of the above

Answer 1

4x2-2x+1

Answer 2

if the value of x that makes the option go zero, makes the equation itself go zero; its a factor

Answer 3

Thanks (:

Answer 4

welcome

Answer 5

2x – 1 = 0 when x=1/2

if the equation goes zero for x=1/2 its a factor

32x3 + 4
1/2
----------
32/8 + 4 = 4+4 = 8 .... first one aint a factor
