Question

Coffecient of x in expansion :(x+y)^3

Answer 1

Answer:  (x+y)³= = x³+ y³+ 3xy(x+y)   [ (a+b)³= a³+b³+3xy(x+y) ]

                  So, here 1 is the coefficient of x³

Step-by-step explanation: As we know the formula of (x+y)³= x³+ y³+ 3xy(x+y) and the value x= 1x. So above in the answer value of x³=1³.

I know that I have alongated the answer. But I think I have given right answer. just brainly wants some explatnation so I have explained.

PLEASE MARK IT AS A BRAINLIEST ANSWER.
