critical f(x,y)=10-8x+5y+3x^2-7xy+2y^2

critical points

f (x, y) = 10 - 8 x + 5 y + 3 x^{2} - 7 x y + 2 y^{2}

(\frac{3}{25}, - \frac{26}{25})

Solution steps

10 - 8 x + 5 y + 3 x^{2} - 7 x y + 2 y^{2}

Find where

\nabla f (x, y)

is equal to zero or undefined

(\frac{3}{25}, - \frac{26}{25})

x^{\frac{2}{3}} (x^{2} - 8)

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

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

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

f (x) = \frac{x + 4}{3 x + 1}
