Question

Pls help quickly!!

Factor completely

3zy²x + y²x - 12zx - 4x


Select one:

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

b. None of these.

c.xy (3z + 1)(y-2)

d. x (3z + 1) (4z-3)

e. x (3z-1) (y + 2)²

Answer 1

- START OF BY TAKING OUT THE X
- THEN IT WOULD BE X[y^2(3z+1)-4(3z+1)]
- TAKE OUT SIMILARITIES IN THE FIRST TWO AND LAST TWO
- THEN PUT 3z+1 TOGETHER.
and y^2-4 together
- y^2-4 becomes (y+4)(y-4)
- that would make the answer x(y+4)(y-4)(3z+1) so OPTION A
