WebLesson Worksheet: Solving Cubic Equations Graphically. In this worksheet, we will practice graphing a cubic equation and using this graph to find its solution or solutions. Use technology to plot the graph of 𝑓 ( 𝑥) = 𝑥 + 5 𝑥 − 1 0 0 , and use this graph to find the solutions to the equation 𝑥 + 5 𝑥 = 1 0 0 to two decimal ... WebSolving cubic equations using graphical method. If you cannot solve the cubic equation by any of the above methods, you can solve it graphically. For that, you need to have an accurate sketch of the given cubic equation. The point(s) where its graph crosses the x-axis, is a solution of the equation.
In a cubic equation, the highest exponent is 3, the equation has 3 solutions/roots, and the equation itself takes the form . While cubics look intimidating and unlike quadratic equation is … See more 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.
