Question: Use OCTAVE solve x 1 , x 2 and x 3 for the following equations: Given z = x^2-y^2, plot the 3D surface for x

Use OCTAVE solve x1, x2 and x3 for the following equations:

0 = x - x + 2x3 - 2 0 = 2x 

Given z = x^2-y^2, plot the 3D surface for x = y with 40 linearly spaced data points from -1 to 1.

0 = x - x + 2x3 - 2 0 = 2x + 6x + 6 0 = 2x + 6x2 - 2x3 +5
