Answer 2

Answer:

In above equation, to convert the denominator in terms variable in numerator only, substitute, a+b+c=y

So, above equation becomes,

x-a2/y-a + y2-b2/y-b + y2-c2/y-c

= 4y

Just for a the sake of cancelling the denominator terms, substitute x=y2 in this, so we get,

y2−a2/y−a + y2−b2/y−b + y2−c2/y−c

= 4y

(y−a)(y+a)/(y−a) + (y−b)(y+b)/(y−b) + (y−c) (y+c)/(y−c) = 4y

(y+a)+(y+b)+(y+c)=4y

3y+a+b+c=4y i.e. y=a+b+c

So, this is the same value as per our assumption which is indeed found to be true.

Hence, x=y2 i.e. x=(a+b+c)2 is the solution of above equation.
