In practice most often you would solve a cubic equation 3rd degree by guessing one solution x 1 dividing the cubic by x x 1 and then solving the resulting quadratic equation 2nd degree as usual. Learn how to factor higher order trinomials. Now click the button Solve Equation to get the solution Step 3.
The polynomial is degree 3 and could be difficult to solve.
If the polynomial equation has a degree that is three or higher start by finding one rational factor or zero. The cubic polynomial is a product of three first-degree polynomials or a product of one first-degree polynomial and another unfactorable second-degree polynomial. Now click the button Solve Equation to get the solution Step 3. There are many approaches to solving polynomials with an x 3 displaystyle x3 term or higher.
