Problem 1: 1. Perform by hand three iterations of the bisection method to find root of the equation: X2 = 1.8x + 25, with the root in the interval [a,b] = [5,101. Provide values of the approximation to the roof after every iteration. 2. Perform by hand three iterations of the Newton-Raphson method to find root of the equation: 14 +20x 19x2 - 3x3, with the initial approximation to the root xo 0.5. Provide values of the the approximation to the root after every iteration
