please explain what the error is also please, I need help asap !

Answer:
B (1)
Step-by-step explanation:
Step One: [tex]\frac{4x-8}{10y} * \frac{3*5y^{2} }{5x-10}[/tex]
Step Two: Simplify [tex]\frac{3*5y^{2} }{5x-10}[/tex]
Step Three: [tex]\frac{4x-8}{10y}[/tex]
Step Four: Simplify [tex]\frac{4x-8}{10y}[/tex]
Step Five: [tex]\frac{2* (x-2)}{5y} * \frac{3y^{2} }{x-2}[/tex]
Final: [tex]\frac{6y}{5}[/tex]
Answer:
option B
Step-by-step explanation:
(4x-8)/10y * 15y^2/(5x-10)= 4(x-2)/2*3y/5(x-2)= 2*3y/5= 6y/5
Option B
Mistake is at step 1
