WebExplanation. a x 2 + b x + c = 0. This is the initial equation. a x 2 + b x = – c. Subtract the variable c from both sides to get rid of the + c on the left. x 2 + b a x = – c a. Divide both sides by a to free x 2 of its coefficient. x 2 + 2 b 2 a x = − c a. Rewrite b a as 2 b 2 a x so that the second term is 2 p q. WebNov 30, 2024 · Generally speaking, when you have to solve a cubic equation, you’ll be presented with it in the form: ax^3 +bx^2 + cx^1+d = 0 ax3 + bx2 + cx1 + d = 0. Each solution for x is called a “root” of the equation. Cubic equations either have one real root or three, although they may be repeated, but there is always at least one solution.
