  • Quadratic Equation (ax² + bx + c = 0)
  • Proportion (a/b = c/x)
  • Percentage (x% of a = b)
  • Pythagorean Theorem (a² + b² = x²)

Step 2: Enter the Values

Once you've selected the equation type, the relevant input fields will appear. Here’s a breakdown of what each equation requires:

  1. Linear Equation:
    • Coefficient (a)
    • Constant (b)
    • Result (c)
  2. Quadratic Equation:
    • Coefficient a (x²)
    • Coefficient b (x)
    • Constant c
  3. Proportion:
    • Numerator a
    • Denominator b
    • Numerator c
  4. Percentage:
    • Total Amount a
    • Part Amount b
  5. Pythagorean Theorem:
    • Side a
    • Side b

Step 3: Click "Calculate"

After entering all the required values, simply click the "Calculate" button to solve for X. The tool will display the equation, solution steps, and the value(s) of X.

Step 4: Reset (Optional)

If you want to solve another equation, click the "Reset" button to clear the inputs and start over.

Example: Solving a Linear Equation

Let’s walk through a quick example of solving a linear equation using this tool. Suppose you want to solve the equation 2x + 3 = 11.

  1. Select the Linear Equation option from the dropdown menu.
  2. Enter the values:
    • Coefficient (a): 2
    • Constant (b): 3
    • Result (c): 11
  3. Click Calculate.

The tool will show the equation: 2x + 3 = 11, and solve for x = 4 with the step-by-step process:

  1. 2x = 11 - 3
  2. 2x = 8
  3. x = 8 / 2
  4. x = 4

Detailed Breakdown of Equation Types

1. Linear Equations

Linear equations are one of the simplest forms of algebraic equations. The general form is ax + b = c, where a, b, and c are constants, and x is the unknown variable. Solving for x involves isolating the variable through basic algebraic operations.

2. Quadratic Equations

A quadratic equation is in the form ax² + bx + c = 0, where a, b, and c are constants. The solution for x can be found using the quadratic formula:x=−b±b2−4ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}x=2a−b±b2−4ac​​

This equation can have two real solutions, one real solution, or two complex solutions based on the discriminant.

3. Proportions

Proportions represent two ratios that are equal. The general form is a/b = c/x, where a, b, and c are known values, and x is the unknown variable. To solve for x, we use cross-multiplication.

4. Percentage Problems

In percentage problems, you are asked to find x when a percentage of a total is known. The general form is x% of a = b, where a is the total amount, and b is the part amount. Solving for x involves simple division.

5. Pythagorean Theorem

The Pythagorean Theorem helps calculate the length of the hypotenuse in a right-angled triangle. The formula is a² + b² = x², where a and b are the lengths of the other two sides, and x is the hypotenuse.

Additional Tips for Best Results

  1. Double-Check Inputs: Always ensure that you’ve entered all values correctly. Missing or incorrect values can lead to incorrect solutions.
  2. Check for Zero: For certain equations, such as linear and proportion equations, make sure that values like a are not zero, as this will cause an invalid solution.
  3. Review Solution Steps: The step-by-step breakdown provided by the tool can help you understand how the solution was derived. This can be helpful if you're learning algebra or trying to verify your manual calculations.
  4. Verify Results: Use the tool’s verification feature to check the solution by substituting the calculated value of x back into the original equation.
