1. What is the Maximum/Minimum Value of Quadratic Equation?

The Maximum/Minimum Value of a Quadratic Equation represents the highest or lowest point on the graph of the quadratic function, depending on whether the coefficient 'a' is negative or positive respectively. This point is known as the vertex of the parabola.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Maximum/Minimum Value} = \frac{(4 \times a \times c) - (b^2)}{4 \times a} \]

Where:

Explanation: This formula calculates the y-coordinate of the vertex of the parabola represented by the quadratic equation ax² + bx + c = 0.

3. Importance of Maximum/Minimum Value Calculation

Details: Finding the maximum or minimum value of a quadratic equation is crucial in optimization problems, physics applications, economics, engineering, and various real-world scenarios where finding optimal solutions is required.

4. Using the Calculator

Tips: Enter the numerical coefficients a, b, and c from your quadratic equation in the form ax² + bx + c = 0. The coefficient 'a' must be non-zero for the calculation to be valid.

5. Frequently Asked Questions (FAQ)

Q1: How do I know if the value is maximum or minimum?
A: If the coefficient 'a' is positive, the value represents the minimum point. If 'a' is negative, it represents the maximum point.

Q2: What if coefficient 'a' is zero?
A: If a = 0, the equation is not quadratic but linear, and this formula does not apply.

Q3: Can this formula be used for any quadratic equation?
A: Yes, this formula works for all quadratic equations in the standard form ax² + bx + c = 0 where a ≠ 0.

Q4: What is the relationship between this formula and the vertex formula?
A: This formula gives the y-coordinate of the vertex, while the x-coordinate is given by -b/(2a).

Q5: Are there practical applications of this calculation?
A: Yes, it's used in various fields including physics (projectile motion), economics (profit maximization), engineering (structural optimization), and computer graphics.
