Mathematical Formulas Used in Algebra Calculator
This tool uses fundamental algebraic formulas to generate accurate results.
1. Addition
Formula:
A + B
Used to combine two values.
2. Subtraction
Formula:
A - B
Used to find the difference between two values.
3. Multiplication
Formula:
A × B
Used for repeated addition or scaling values.
4. Division
Formula:
A ÷ B
Used to split values into equal parts. (Note: B cannot be zero)
5. Quadratic Equation Formula
One of the most important features of this calculator is solving quadratic equations.
Standard Form:
Ax² + Bx + C = 0
Quadratic Formula:
x = (-B ± √(B² - 4AC)) ÷ 2A
Discriminant:
D = B² - 4AC
- If D > 0 → Two real roots
- If D = 0 → One real root
- If D < 0 → No real real solutions
This calculator automatically computes both roots (x1 and x2) when real solutions exist.
Example Calculations
Let’s understand how this tool works with real examples.
Example 1: Addition
Input:
- A = 10
- B = 5
Operation: A + B
Result:
10 + 5 = 15
Example 2: Multiplication
Input:
- A = 6
- B = 7
Operation: A × B
Result:
6 × 7 = 42
Example 3: Division
Input:
- A = 20
- B = 4
Operation: A ÷ B
Result:
20 ÷ 4 = 5
Example 4: Subtraction
Input:
- A = 15
- B = 9
Operation: A - B
Result:
15 - 9 = 6
Example 5: Quadratic Equation
Input:
- A = 1
- B = -5
- C = 6
Step 1: Discriminant
D = (-5)² - 4(1)(6) = 25 - 24 = 1
Step 2: Roots
x = (5 ± √1) / 2
- x1 = (5 + 1)/2 = 3
- x2 = (5 - 1)/2 = 2
Final Answer:
x1 = 3, x2 = 2
