Two lin alg question help please? - lin x cel vc-211a driver
1. Using Gauss-Jordan systems for the solution to get rid of the following
x - 2y + z = -6
2x - 3y = 7
-x + 3y - 3x = 11
2. Determine the polynomial whose graph through the points (1.4) (2.0), (3.12)
For # 1 I think a solution is infinite, but I think I need a finish.
And # 2 I guess, to use the polynomial curve fitting?

Lin X Cel Vc-211a Driver Two Lin Alg Question Help Please?

Use the first equation x different remedy:
x - 2y + z = -6
...... y - 2z = 19 (2 to 2 * 1)
...... y - 2z = 5 (3 + 1).
The conclusion that these equations are compatible, there are no solutions.

Yes, you use the Lagrange interpolation:
p (x) =
... 4 (x-2) (x-3) / [(1-2) (1-3)] +
... 0 (x-1) (x-3) / [(2-1) (2-3)] +
.12 (X-1) (x-2) / [(3-1) (3-2)],
and simplification.
