Which of the following is a situation in which an equation cannot be solved using the quadratic formula? a. the right-hand side of the equation is zero. b. the coefficient of the x2-term is 1. c. one term of the polynomial has a degree of 3. d. the coefficient of the x-term is zero.

The quadratic formula is used to calculate the roots of equations with degree 2, ie. in the form y = ax² + bx + c, where a,b,c ∈ R (real numbers). So, the answer is C.
