Question

The least possible value for
x
2
−2xy+2
y
2
−6y
x2−2xy+2y2−6y​

Answer 1

$$f_x^{'} = 2x+2y = 2(x+y) = 0$$

⟹x=−y

f

y

′

=2x+4y+6=0

or,2y=−6

y=−3 and x=3

Putting in the equation, we get

9−18+18−18+10

⟹1

Answer 2

Answer:

$$f_x^{'} = 2x+2y = 2(x+y) = 0$$

⟹x=−y

fy′  =2x+4y+6=0

or,2y=−6

y=−3 and x=3

Putting in the equation, we get

9−18+18−18+10

⟹1
