Introduction
In mathematics, equations are a fundamental concept that help us solve problems and understand various phenomena. One of the most common types of equations is the quadratic equation, which is expressed in the form ax^2 + bx + c = 0. In this article, we will explore how to express the equation x = √x as a quadratic equation and find the value of a + b + c.
Expressing x = √x as a Quadratic Equation
To express x = √x as a quadratic equation, we need to start by isolating the square root term. We can do this by squaring both sides of the equation:
x = √x x^2 = (√x)^2 x^2 = x
Now, we can rearrange the equation to get:
x^2 - x = 0
This is a quadratic equation in the form ax^2 + bx + c = 0, where a = 1, b = -1, and c = 0.
Finding the Value of a + b + c
Now that we have expressed x = √x as a quadratic equation, we can find the value of a + b + c. We simply need to add the values of a, b, and c:
a + b + c = 1 + (-1) + 0 a + b + c = 0
Therefore, the value of a + b + c is 0.
Conclusion
In this article, we have explored how to express the equation x = √x as a quadratic equation and find the value of a + b + c. We have seen that the value of a + b + c is 0. This is a simple yet important concept in mathematics that can help us solve problems and understand various phenomena.
