In the Solver parameters dialogue box, do the following and press Solve.Just after typing the equation in cell F3, click on to solver which is under the Analysis option of the Data tab.Let`s solve the same equation for a better understanding. You can also use the Solver feature of Excel to solve quadratic equations.

After the Goal Seek completes its operation you will see the initial value of X and the cell where the formula was placed is changed.The Goal Seek feature will do some irritations for the final value of Y which is set as 12 in this example.Now, under the Data tab click on the Goal Seek option under the Forecast option.After that write the equation in cell F3 with respect to the cells of coefficients and the initial value of X.
We will see how this equation can be solved with the Goal Seek feature. Let`s solve a quadratic equation which is Y=3x 2+6x-5.

You can also use the Solver feature of Excel to solve cubic equations. Solve Cubic Equation in Excel using Solver Now the initial value is showing the value of X when the value of Y becomes 15. The Goal Seek feature will do some iterations for the final value of Y which is set as 15 in this example.In the Goal Seek dialogue box, insert the inputs as follows and press on OK.Now, under the Data tab click on to the Goal Seek option under the Forecast option.After that write the polynomial equation in cell G3 with respect to the cells of coefficients and the initial value of X.Set the initial value of X as “0” in cell B6.First set the coefficients in different cells.We will use the Excel Goal Seek feature here to solve the equation. We will solve this equation for finding the value of “X” with a specific value of “Y”. Let`s say we have a cubic equation which is Y=5x 3-2x 2+3x-6.

Different kind of polynomial equations example is given below. The Polynomial equations don’t contain a negative power of its variables. If you want your variables to go negative, uncheck this box.Further Readings Solving Polynomial Equations in ExcelĪ polynomial equation/function can be quadratic, linear, quartic, cubic, and so on. You can also use the checkbox in the main Solver window to make sure that all of the values that you didn't specify constraints for are non-negative. You don't have to add a constraint for each cell. If you want six variables to have values over 10, for example, you can select them all and tell Solver that they must be greater than or equal to 11. It's important to remember that you can select multiple cells for Cell Reference. So if you have three cells, you'll end up with the numbers 1, 2, and 3 (but not necessarily in that order)įinally, add the value for the constraint.
But it also specifies that they must be between 1 and the number of cells. It specifies that every cell in the range that you select for Cell Reference must be a different number.
