Question

x (x - 2 y) x (x square + 2 X Y + 4 y square equals to​

Answer 1

Answer:

For a parabola,

dx

dy

=0 at the vertex. Hence,

2x+2y

dx

dy

−2x

dx

dy

−2y−4−4

dx

dy

=0

2x−2y−4=0

x=2+y

Putting it back in the equation, we get

(2+y)

2

+y

2

−2y(y+2)−4(y+2)−4y+4=0

4+4y+y

2

+y

−4y−4y−8−4y+4=0

−8y=0

y=0

x=2
