Question

Factor: 12x + 8y - 4z

here are the ones to pick from

1. 4(x + y + z)
2. 4( 3x - 2y + z)
3. 2( 3x + 4y - 2z)
4. 4( 3x + 2y - z)

Answer 1

4( 3x + 2y - z)

Explanation:

Since the Factor is Asked, all you need to do is take out the common value to let the equation reach the simplest form.

As the entire equation has 4 in common we can take it out and divide the equation by 4 to get the other factor.

(12x+8y-4z)/4 = ( 3x + 2y - z)

Therefore, the factors are 4 and ( 3x + 2y - z)
