Question

(x+y)(x+y)-z(x+y)=a(x+y-z) then a=

Answer 1

Answer:

a = x + y

Step-by-step explanation:

Given that-

(x + y)(x + y) - z(x + y) = a(x + y - z)

Take common (x + y)

(x + y)[(x + y) - z] = a(x + y - z)

(x + y)(x + y - z) = a(x + y -z)

(x + y - z) cancels from both sides

(x + y) = a

Hence, a = x + y
