In a cubic equation, the highest exponent is 3, the equation has 3 solutions/roots, and the equation itself takes the form a x 3 + b x 2 + c x + d = 0 +bx^+cx+d=0> . [1] X Research source While cubics look intimidating and unlike quadratic equation is quite difficult to solve, using the right approach (and a good amount of foundational knowledge) can tame even the trickiest cubics. You can try, among other options, using the quadratic formula, finding integer solutions, or identifying discriminants.
