critical 4x^4+4y^4-xy

critical points

4 x^{4} + 4 y^{4} - x y

(0, 0), (- \frac{1}{4}, - \frac{1}{4}), (\frac{1}{4}, \frac{1}{4})

Solution steps

4 x^{4} + 4 y^{4} - x y

Find where

\nabla f (x, y)

is equal to zero or undefined

(0, 0), (- \frac{1}{4}, - \frac{1}{4}), (\frac{1}{4}, \frac{1}{4})

f (x, y) = y^{3} + x^{2} - 6 x y + 3 x + 6 y - 7

y = \frac{x}{( x + 1 ) ^{2}}

- 4 n \cdot \frac{x ln ( x )}{1 - x}

y = 3 - I n (2 x + 7)

x^{\frac{2}{5}} (x - 10)
