Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
