What is the answer for c and d?

() (d) Write the quadratic polynomial found in part (a) in the form z = a/(b z), for some constants a > 0 and b > 0, and use this to iteratively construct a series of continued fractions. In doing so, with successive truncation evaluate these to four decimal places. Stop once these evaluations become repeated. Since x solves the quadratic polynomial, give the true value of this approximation process. In part (c) the quadratic polynomial found in part (a) was written in the form z = a/(b x), alternatively b z = a/z. Use this latter form to iteratively construct a series of continued fractions. In doing so, with successive truncation evaluate these to two decimal places. Stop once these evaluations become repeated. Since z solves the quadratic polynomial, give the true value of this approximation process
