Factor completely 4x4 - 24x3 + 36x2.

4x2(x - 3)2

4(x - 3)2

4x2(x + 3)(x - 3)

4x(x2 - 6x + 9)

Answer 1

i would recommend starting by taking out 4x^2 so that your equation will become 4x^2(x^2 - 6x + 9)

Answer 2

follow the same steps as before

Answer 3

and from there all you need to factor is (x^2 - 6x +9)

Answer 4

hint: this is also a perfect square

Answer 5

4x2(x - 3)2?
