critical f(x)=x^2-6xy+10y^2-4y

critical points

f (x) = x^{2} - 6 x y + 10 y^{2} - 4 y

(6, 2)

Solution steps

x^{2} - 6 x y + 10 y^{2} - 4 y

Find where

\nabla f (x, y)

is equal to zero or undefined

(6, 2)

x^{3} - x + 1

f (x) = x^{3} - 12 x^{2} + 36 x + 5

f (x, y) = - 3 x^{2} y + y^{3} - 3 x^{2} - 3 y^{2} + 1

2 x + \frac{72}{x}

f (x) = - \frac{2 ( x ^{2} - 1 )}{x ^{2} - 4}
