A cubic equation can be solved in the following ways: Finding Integer Solutions with Factor Lists; Using the Graphical method; Solving the cubic equation using factors of the polynomial. Example: Find the roots of equation f(x) = 3x 3 −16x 2 + 23x − 6 = 0. Solution: WebSOLVING CUBIC EQUATIONS A cubic expression is an expression of the form ax3 + bx2 +cx + d. The following are all examples of expressions we will be working with: 2x 3 – 16, x – 2x2 – 3x, x3 + 4x2 – 16, 2x3 + x – 3. Remember that some quadratic expressions can be factorised into two linear factors: e.g. 2x2 – 3x + 1 = (2x – 1)(x – 1)
