Answer:
Choice B. only Shota
Step-by-step explanation:
16z^2 - 40z
the greatest common value is 8z
8z (2z^2 -5)
24z^2 - 40z
the greatest common value is 8z
8z (3z^2 -5)
[tex]\frac{8z (2z^2 -5)}{8z (3z^2 -5)}[/tex]
8z / 8z = 1
= [tex]\frac{8z}{8z}[/tex] x [tex]\frac{2z^2 -5}{3z^2 -5}[/tex] = 1 x [tex]\frac{2z^2 -5}{3z^2 -5}[/tex] = [tex]\frac{2z^2 -5}{3z^2 -5}[/tex] (Shota)
