Factorise completely:
(a) 8m - 50 n2

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

i would need to see the dot plot : )
