Hi Aarthi,
Use (a+b+c)^2 = a^2+b^2+c^2 +2ab+2ac+2bc
And then try to solve.
Practice once on your own as i have given you the hint.
It will be really helpful to solve on your own as you can tackle other such types too later in the exams.
Hope it helped.
Let me know in the comments if u still need any help.
Cheers !!!
