10y = 70
y = 7
When x = - 5 and y = 7, z = 3 x (- 5)3 - 5 x (7)2 - 225 x (- 5) + 70 x 7 + 23 = - 375 - 245 + 1125 + 490 + 23 = 1018
When x = 5 and y = 7, z = 3 x (5)3 - 5 x (7)2 - 225 x 5 + 70 x 7 + 23 = 375 - 245 - 1125 + 490 + 23 = - 482
Second order condition for maxima is: zxx < 0 and zyy < 0. Second order condition for minima is: zxx > 0 and zyy > 0.
zxx = \partial/\partialx(zx) = 18x
When x = - 5, zxx = 18 x (-5) = - 90 < 0
When x = 5, zxx = 18 x 5 = 90 > 0
zyy = \partial/\partialy(zy) = - 10 < 0.
Therefore, when x = -5 and y = 7, it is a minima. But when x = 5 and y = 7, the solution is neither maxima nor minima.
