How to solve for x cubic function

WebA cubic equation is an algebraic equation of third-degree. The general form of a cubic function is: f (x) = ax 3 + bx 2 + cx 1 + d. And the cubic equation has the form of ax 3 + bx 2 + cx + d = 0, where a, b and c are the coefficients and d is the constant. How to Solve Cubic … WebUse Algebra to solve: A "root" is when y is zero: 2x+1 = 0 Subtract 1 from both sides: 2x = −1 Divide both sides by 2: x = −1/2 And that is the solution: x = −1/2 (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2. By experience, or simply guesswork.
