D= -16 < 0 fxx = -2, fxy = 4, fyy=0 saddle point at. (x,y) = (-1,-2) fxx. (x) = 8x. Con- nuing on, we have f. ′′. (x) = d dx. (. 8x. ) = 8; f. ′′′. (x) ... f(x)=(x − 2)2 ln(x − 2). 18. f(x) = x2 − 4 x2. 19. f(x) = x2 − 4x + 3 x2 ... We can now square root both sides to give: x+4=0. Now subtracting 4 from both sides gives x=-4. This means that for x^2+8x+16=0 we have found that x=-4.
