The results in cells A4 and A5 are the two roots of the quadratic equation: x = 1 and x = 1.5. In cell A2, type '-5' (coefficient of the linear term).In cell A1, type '2' (coefficient of the squared term).Let's solve the quadratic equation 2x^2 - 5x + 3 = 0 using the LINEST() function: If your Excel version doesn't support the QUAD() function, you can use the LINEST() function, as described in the next section. After taking a few days to get everything set up, all the while wondering where to start, I decided to work my way through my math cheat sheets and make. Note: The QUAD() function is only available in Excel 2013 and later versions.

Press Enter, and Excel will calculate the roots of the quadratic equation.In cell A4, type the following formula: =QUAD(A1, A2, A3).In cell A3, type the constant term (c).In cell A2, type the coefficient of the linear term (b).In cell A1, type the coefficient of the squared term (a).Open Microsoft Excel and create a new spreadsheet.The standard representation of the cubic equation is ax3+bx2+cx+d 0 where a, b, c, and d are real numbers. Follow these steps to find the roots of a quadratic equation in Excel: Using QUAD() function Cubic Equation is a mathematical equation in which a polynomial of degree 3 is equated to a constant or another polynomial of maximum degree 2. To solve a quadratic equation in Excel, you can use the built-in formula '=QUAD()' or the more versatile '=LINEST()' function. Step 4: Equate each factor to zero and figure out the roots upon simplification.How to Solve a Quadratic Equation in Excel Step 3: Use these factors and rewrite the equation in the factored form. Step 2: Determine the two factors of this product that add up to 'b'. Once you are here, follow these steps to a tee and you will progress your way to the roots with ease. You can also use algebraic identities at this stage if the equation permits. Either the given equations are already in this form, or you need to rearrange them to arrive at this form. Keep to the standard form of a quadratic equation: ax 2 + bx + c = 0, where x is the unknown, and a ≠ 0, b, and c are numerical coefficients.
