x = [-b ± √(bac)]/2a. Then we look at how cubic equations can be solved by spotting factors and using a method called synthetic division ©1 c2P0D1 y1C rK4umt Nat YS1okf otkw Za 6rweG 4L 2L eCo. So use quadratic formula and solve. mc-TY-cubicequations ax3 + bx2 + cx + d =where a 6=All cubic equations have either one real root, or three real roots. DefinitionA cubic polynomial (cubic for short) is Cubic equations. Solve each of the following cubic equations) x3 + 2xx=) 2xxx +=) xxx +=) 4x SOLVING CUBIC EQUATIONS A cubic expression is an expression of the form ax3 + bx2 +cx + d. In this unit we explore why this is so. A cubic equation has the form. First, write your equation as a polynomial: A V3 + B V2 + C V + D =MethodIteration) Write the equation as V=f(V) V = -(1/C) (A V3 + B V2 + D) SOLVING CUBIC EQUATIONS WORKSHEET.

The other roots can be determined by solving the quadratic equationxx +=This quadratic equation can not be solved by factoring. The following are all examples of expressions we will be working withx– Polynomials IThe Cubic Formula. In this unit we explore why this is so. Yan Tao.
