Answer 2

Hii !!

Solution :-

(x + y)² = 4

diffrentiating with respect to x .

dy/dx = d (x+y)² /dx = d(4)/dx

=> d(x²+ y²+ 2xy)/dx = 0

=> 2x + 2y*dy/dx +2{yd(x)/dx +x d(y)*d(x) =0

=> 2x + 2y*dy/dx + 2y + 2x* + 2 *x*dy/dx = 0

=> 2y*dy/dx + 2 *x*dy/dx = -(2x + 2y )

=> 2dy/(dx) (y+x) = -2(x + y)

=> dy/dx = - 1 Answer
