1. Problem Write a function that given the coefficients of a quadratic polynomial ax2+bx+c, returns the real roots: Option [(Double, solve (2, solve (1, solve (1, -2, -4) 0, 1) 0, -1) Double) resO: res1 Option [ (Double, Double)J None res2: Option [ (Double, Double)Some ( (1.0,-1.0)) > . Some ((2.0,-1.0)) Notes: Our version of solve returns an option containing a tuple. Options and tuples are discussed here: Options. Maps and Tuples. When there are two real roots, as in the first example, solve returns a Some object containing the roots as a pair of doubles Whem ihcre are no noot, as in hte second cuampl, solve retuns None How would you modify solve to return complex roots
