Bhaskara's formula
Solve quadratic equations step by step.
How to use the Bhaskara Formula?
The Bhaskara Formula is a solving method used to determine the roots of a quadratic equation. It is taught worldwide, dividing the solution into two large steps that are easy to memorize.
Step 1: The Discriminant (Delta)
First, we identify who the letters (coefficients) a, b, and c of the equation are. Then, we calculate Delta using the formula:Δ = b² - 4acIf this number turns out negative, we stop the calculation there, because it will be impossible to take its square root in the next step.
Step 2: The Bhaskara Formula
With the Delta in hand, we applied the main formula:x = (-b ± √Δ) / 2a. The symbol \"±\" (plus or minus) exists because we will have to unfold the calculation on two fronts: one we will do the addition calculation, which we will callx'. And the other one we will do the subtraction, calling itx''. Our calculator sets up this entire step-by-step visually for you to learn and paste into your notebook!
