Answer:

a)2m²+20m+5²

b)m²-m+1/2²

___________________________________________

Step-by-step explanation:

a)[ Identity to be used must be (a+b)²= a²+2ab+b²]

Here a=2m and b=5

(2m+5)²= 2m²+(2 x 2m x 5)+5²

            = 2m²+20m+5²

b)[ Identity to be used must be (a-b)²= a²-2ab+b²]

     Here a=m and b=1/2

     (m-1/2)²=m²-2 x m x ½+1/2²

                  =m²-m+1/2²

There you go that's all  ✌
