critical f(x)=x^2+2xy+2y^2

critical points

f (x) = x^{2} + 2 x y + 2 y^{2}

(0, 0)

Solution steps

x^{2} + 2 x y + 2 y^{2}

Find where

\nabla f (x, y)

is equal to zero or undefined

(0, 0)

f (x, y) = e^{4 y - x^{2} - y^{2}}

f (x, y) = 4 x^{2} + 3 x y^{2} + 4 y + 24

f (x) = 6 x^{4} + 2 x^{3}

(x - 3)^{2} (x + 8)

e^{x^{2} - y^{2}}

What is the critical f(x)=x^2+2xy+2y^2 ?
