Convert the augmented matrix [5 -3 4 2 || || -3 0 -5 to the equivalent linear system. Use x1, x2, and x3 to enter the variables x₁, x2, and x3. 8:8

Let -1 -3 A = -8 2 -2 4 and -6 -9 -1 B %3D -5 4 10 then use the matrices above to perform matrix multiplication AB ||

Find the matrix of the quadratic form. Assume x is in R³. a. 2x² + 3x²2 - 9x²3 - 10x₁x×2 + 18x₁×3 − 12×2×3 b. 2x1x2 + 12x₁X3 - 18x2x3 a. The matrix of the quadratic form 2x² + 3x2 -9x3 - 10x₁x2 + 18x₁ x3 - 12x₂x3 is (Simplify your answer.) Part 1 of 2

AB BA If A = False [4] and then B = [44] -2 -2 and True or False: AB = BA for any two square matrices A and B of the same size.
