Question: Use the following LU factorization to (a) compute the determinant and (b) solve [A]{x} = {b} with {b}T = 10 50 26. [A] = [L][U]

Use the following LU factorization to (a) compute the determinant and (b) solve [A]{x} = {b} with {b}T = ⌊−10 50 −26⌋.

[A] = [L][U] = 1 0.6667 -0.3333 [0 3 [ X 1

[A] = [L][U] = 1 0.6667 -0.3333 [0 3 [ X 1 -0.3636 1 -2 7.3333 1 -4.6667 3.6364
