help explain please. thank you

Consider the simultaneous equations f(x,y) = (xy - 4x2 + 3x - 1) = 0, 82(x,y) = (6x2 9xy 5) = 0. (a). For solving these equations using Newton's method, one needs the Jacobian matrix. Obtain the Jacobian matrix for the system of equations. (b). The solution to the system of equations can be obtained without iterations using the Tearing method. Express y in terms of x and obtain a master equation in x [(x) = 0). How many roots does the master equation have? (c). The roots of the master equation can be obtained using the roots(coeff) function in Matlab. Write the coeff vector for the master equation and obtain the roots
