Understanding Quadratic Equations x²-11x+28=0
What is a Quadratic Equation?
Certainly! It seems like there might be a formatting issue or omission in your message. Please provide the quadratic equation or the specific part you’d like me to rewrite, and I’ll be happy to assist you.
ax^2 + bx + c = 0
In this equation, ‘a,’ ‘b,’ and ‘c’ represent coefficients, while ‘x’ stands for the variable. The equation x²-11x+28=0 precisely aligns with this standard form.
General Form of a Quadratic Equation
Certainly! It is crucial to grasp the general form of a quadratic equation as it serves as the cornerstone for understanding these mathematical expressions. By familiarizing ourselves with this structure, we can readily discern the coefficients ‘a,’ ‘b,’ and ‘c.’ In our particular equation, ‘a’ takes the value of 1, ‘b’ is -11, and ‘c’ is 28.
Solving Quadratic Equation x²-11x+28=0
Quadratic equations are a realm of mathematical problems that can be tackled using various methods. Let’s explore two prominent techniques:
Factoring
Factoring is a technique used to solve quadratic equations that are amenable to simplification. Nevertheless, when confronted with more intricate equations such as x² – 11x + 28 = 0, factoring might not be the most direct or straightforward method.
Quadratic Formula
The quadratic formula emerges as a versatile and universally applicable approach to solving quadratic equations. This formula, often called upon, is:
x = (-b ± √(b^2 – 4ac)) / 2a
With this formula, we obtain the roots of the equation, representing the values of ‘x’ that render the equation equal to zero.
x^2-11x+28=0: A Case Study
Intriguingly, we now turn our attention to the specific equation x2-11x+28=0. Our exploration will involve a step-by-step analysis using the quadratic formula.
Step 1: Identifying the Coefficients
To initiate this journey, we must first identify the coefficients. In the equation at hand, ‘a’ is 1, ‘b’ is -11, and ‘c’ is 28.
Step 2: Applying the Quadratic Formula
With the coefficients now in our grasp, we can proceed to apply the quadratic formula. The equation takes shape as follows:
x = (-(-11) ± √((-11)^2 – 4 * 1 * 28)) / (2 * 1)
In the pursuit of a solution, we simplify the equation, leading to:
x = (11 ± √(121 – 112)) / 2
x = (11 ± √9) / 2
Step 3: Finding the Roots
As the equation begins to crystallize, we uncover two potential solutions:
- x = (11 + 3) / 2 = 7
- x = (11 – 3) / 2 = 4
Thus, the roots of the equation x2-11x+28=0 are revealed as x = 7 and x = 4.
Graphical Representation of Quadratic Equations
Within the domain of quadratic equations, the graphical representation typically manifests as a parabola—a curved shape resembling the letter U. This U-shaped curve imparts crucial information about the characteristics of these equations, and the vertex serves as a pivotal point, indicating either the minimum or maximum of the parabola.
