Answer:
2(4m-25n2)
Step-by-step explanation:
To factorise,we will have to know the value that can divide both variables given
But based on this question,we have different variables that is m and n
So we don't have to deal with that but with the numbers which means that we will only deal with the numbers ignoring the letters
8m-50n2
So the only number that can divide the two is 2
2(4m-25n2)
This cannot be solved further so the final answer is 2(4m-25n2)
I hope this will help you
