Quadratic Equation For 0 = 0.25x2 - 8x
Introduction
A quadratic equation is a polynomial equation of degree two, which means the highest power of the variable is two. It is a fundamental concept in mathematics and has numerous applications in various fields, including physics, engineering, and economics. In this article, we will focus on solving a quadratic equation of the form 0 = 0.25x^2 - 8x.
Understanding Quadratic Equations
A quadratic equation can be written in the general form:
ax^2 + bx + c = 0
where a, b, and c are constants, and x is the variable. The equation 0 = 0.25x^2 - 8x is a specific case of a quadratic equation, where a = 0.25, b = -8, and c = 0.
Solving the Quadratic Equation
To solve the quadratic equation 0 = 0.25x^2 - 8x, we can use various methods, including factoring, completing the square, and the quadratic formula. In this article, we will use the quadratic formula to solve the equation.
The Quadratic Formula
The quadratic formula is a mathematical formula that provides the solutions to a quadratic equation. It is given by:
x = (-b ± √(b^2 - 4ac)) / 2a
where a, b, and c are the constants in the quadratic equation.
Applying the Quadratic Formula
To apply the quadratic formula, we need to substitute the values of a, b, and c into the formula. In this case, a = 0.25, b = -8, and c = 0.
x = (8 ± √((-8)^2 - 4(0.25)(0))) / (2(0.25)) x = (8 ± √(64 - 0)) / 0.5 x = (8 ± √64) / 0.5 x = (8 ± 8) / 0.5
Simplifying the Solutions
Now, we can simplify the solutions by evaluating the expressions.
x = (8 + 8) / 0.5 x = 16 / 0.5 x = 32
x = (8 - 8) / 0.5 x = 0 / 0.5 x = 0
Conclusion
In this article, we have solved the quadratic equation 0 = 0.25x^2 - 8x using the quadratic formula. We have found two solutions, x = 32 and x = 0. The quadratic formula is a powerful tool for solving quadratic equations, and it has numerous applications in various fields.
