📝 Answered - Which statement best describes the equation $x^3+x^3-14=0$? A. The equation is quadratic in form because it is a fifth-degree polynomial. B. The equation is quadratic in form because the difference of the exponent of the lead term and the exponent of the middle term is 2. C. The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial. D. The equation is not quadratic in form because the exponent of the lead term is not the square of the exponent of the middle term.
