Question

verify the identity (a-b)^2=a^2-2ab+b^2 where a=6m ,b=5m​

Answer 1

Answer:

6^2-2(6)(5)+5^2

36-60+25

61-60= 1

hope it helps

Answer 2

Answer:

Answer is given below....

Step-by-step explanation:

$a=6m\\b=5m\\\\(a-b)^2=(6m-5m)^2\\a^2+b^2-2ab=m^2\\(6m)^2+(5m)^2-2(6m)(5m)=m^2\\36m^2+25m^2-60 m^2=m^2\\m^2=m^2$

Hence proved.

Hope this helps!
