critical f(x,y)=x^2+2axy+y^2

critical points

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

(0, 0)

Solution steps

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

Find where

\nabla f (x, y)

is equal to zero or undefined

(0, 0)

f (x) = 4 x^{3} - 33 x^{2} - 240 x + 9

f (x) = - 10 x^{2} + 8 x y + 32 x - 2 y^{2}

\frac{2}{x ^{2} + 4}

(x + 5)^{\frac{2}{3}}

f (x) = - 2 x^{2} ln (x) + 21 x^{2}

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