critical f(x)=-4x^2+2y^2+3x+8y-2

critical points

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

(\frac{3}{8}, - 2)

Solution steps

- 4 x^{2} + 2 y^{2} + 3 x + 8 y - 2

Find where

\nabla f (x, y)

is equal to zero or undefined

(\frac{3}{8}, - 2)

f (x) = 3 x^{\frac{2}{3}} - x^{2}

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

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

\frac{5 x}{x ^{2} - 25}

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