Transcribed Image Text:2. It is desired to obtain the real-valued roots of
S(2) = 0, f(x) = ( - 6r-5x2 + 6r- 4V+ 10+
(a). Work with y = V to get a polynomial g(y) from f(r) such that f(x) g(y)/y². Compute
the roots of g(y) = 0 using the Matlab command roots(coeff).
(b). Compute f(r) for each root of g(y) = 0 (r y²) and identify those roots for which f(r) = 0.
This will not be the case with all roots of g(y) = 0.
(c). Confirm these roots using Matlab function fzero using suitable guesses for r.
