Find the multiple roots of the equation with the aid of Newton-Raphson. Start with an initial approximation Xo = 0 and 3 iterations with four decimal places 27x5+27x++36x3+28x2+9x+100=0 -7 -3 0 -1 * 6 points 1-Solve the following system of linear equations corrects up to four decimal places using the Gauss-Seidel iterative procedure. Take x1=X2=X3=0 as the initial solution vector and 3 iterations 20x1 + x2 - 2x3 = 15 3x1 + 20x2 - X3 = -18 2X1 - 3x2 + 20x3 = 10 0.8 -1 0.2 1 -0.8 0.5 -0.2 3-1
