Need asap. Use methods of undetermined coefficients Or methods of variations of parameter in solving the problem

Determine the roots of the following simultaneous nonlinear equations using (a) fixed-point iteration and (b) the Newton-Raphson method: y= x²+x+ 0.75 y+5xy = x² Employ initial guesses of x = y = 1.2 and discuss the results. Hints: The functions can be plotted (y versus x). The plot indicates that there are three real roots at about (-0.6, -0.18), (-0.19, 0.6), and (1.37, 0.24). -0.5 2 0.5 1 1.5 a) Put equations under these forms to solve and use x = y = 1.2 as initial guess: x=√x+0.75-y x² 1+5x b) Use the forms of u and v below to obtain the Jacobian. Use the same initial guess as in a). Iterate till & is close to 10-5 u(x, y) = x² + x + 0.75-y v(x, y) = x²-y-5xy

Find the zeros of the function algebraically
