Most of the time, the problem you will need to solve will be more complex than a simple application of a formula or function.

We will now repeat the same operation for “ x2 ” by copying, pasting and changing “+” sign into a “ – “minus sign in the formula in Cell B12 as =(-B8-SQRT(B8^2-4*B7*B9))/(2*B7)įigure 5a: Formula for the negative root of the equationįigure 5b: Solved quadratic equation Instant Connection to an Expert through our Excelchat Service.

We will type this formula into Cell B11 =(-B8+SQRT(B8^2-4*B7*B9))/(2*B7)įigure 4a: Formula for the positive root of the equationįigure 4b: Answer for the positive root of equation.

We will now prepare a table for the roots of “X” which are “x1” and “x2”, and ascribing values for the variables in the equation of “X” which are “a, b, and c”.

To do this, we will type in our quadratic equation y = a + bx + cx^2 and also define the root of the variable “ X ” by typing this quadratic formula x0 = /2a.

This tutorial will teach use how to solve quadratic equation in excel.įigure 1: Solving quadratic equations Data for Solving Quadratic Equation Thereafter, we would use this quadratic formula to solve for X using some given roots of the equation. X), then we would define X using a formula. We can solve quadratic equations in excel by inputting an equation that contains our variable (e.g.
