Formula & Methodology
The formula for solving for zero is based on the quadratic formula: x = [-b ± sqrt(b^2 – 4ac)] / (2a). Our calculator uses this formula to find the value of x that makes the equation equal to zero.
Real-World Examples
Example 1: Solving for x in 2x + 5 = 0
Enter 2 in the calculator, and the result will be x = -2.5.
Example 2: Solving for x in x^2 – 3x – 4 = 0
Enter 1 in the calculator, and the result will be x = -1 or x = 4.
Example 3: Solving for x in 2x^2 + 3x – 1 = 0
Enter 2 in the calculator, and the result will be x = -0.5 or x = -1.
