Let`s say we have 3 equations where the values of x, y, and z are unknown. We can use a matrix system to solve a set of linear equations in excel. Solve Linear Equations in Excel with Matrix System In the below picture we calculate the roots of the quadratic functions. By using this formula directly we can find the roots of the quadratic function. The format of a quadratic equation is x=(-b±√(b^2-4ac))/2a. Solve Quadratic Equation in Excel using Formula 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.

The below result will be found after the operation.

As it is a non-linear equation the solving method was selected as GRG Nonlinear.

In the Solver Parameters dialogue box, do the following and press the Solve option.

Just after typing the equation in cell G3, click on to solver which is under the Analysis option of the Data tab.

Let`s solve the previous equation for a better understanding. 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.
