critical x^2-6xy+2y^2+10x+2y-5

critical points

x^{2} - 6 x y + 2 y^{2} + 10 x + 2 y - 5

(\frac{13}{7}, \frac{16}{7})

Solution steps

x^{2} - 6 x y + 2 y^{2} + 10 x + 2 y - 5

Find where

\nabla f (x, y)

is equal to zero or undefined

(\frac{13}{7}, \frac{16}{7})

x^{2} - x - ln (x)

f (x) = - 2 x^{2} + 8 x + 7

f (x) = 2 x - x

y = x^{2} - 4 x - 1

f (x) = 3 x^{2} + 8 x + 4
