Answer:
(z+2)(z+3)(x-8)
Step-by-step explanation:
z² + 5z + 6 can be factored into (z+3)(z+2)
zx + 2x − 8z-16 can be factored into (x-8)(z+2)
the LCM would be (z+2)(z+3)(x-8)
if you were to multiply the two expressions together, you would multiply (z+2)^2, which is not necessary for LCM, which is why you factor them first
