How factor the following trinomials completely which is 4x2-24x plus 32?

Answer 1

Dividing all terms by 4 gives: x2-6x+8 = (x-2)(x-4) when factored

Answer 2

Divide both terms by 24.

24(9x3 +1)

Answer 3

First take out the common factor (4):

4(6x2 + 2x + 1)

6x2 + 2x + 1 cannot be factored, so 4(6x2 + 2x + 1) is as far as you can get with factoring.

Answer 4

3x2 + 24 + 16 = 3x2 + 40 which cannot be factorised.

Answer 5

2(x + 3)(x^2 + 4)

Answer 6

8x2(x + 3)
