What Constitutes a Quadratic Equation x2-11x+28=0?

Before we embark on deciphering the specifics of our equation, let’s take a moment to revisit the core concept of quadratic equations. A quadratic equation is a polynomial equation of the second degree, typically represented in the form ax^2 + bx + c = 0. Here, ‘a,’ ‘b,’ and ‘c’ are constants, while ‘x’ stands as the variable we aim to solve for.


Factoring the Equation: A Methodical Approach

To unlock the solution to the quadratic equation x2-11x+28=0, we will employ the method of factoring, which is a fundamental technique used to deconstruct complex equations into simpler components.

Step 1: Identifying the Coefficients

Our equation presents ‘a’ as 1, ‘b’ as -11, and ‘c’ as 28. The first step in factoring involves finding two numbers whose sum equals the coefficient of ‘x’ (in this case, -11), and whose product equals the constant term ‘c’ (which is 28).

Step 2: Discovering the Factors

Through careful consideration, we identify that the two numbers which satisfy these criteria are -7 and -4. This is because the sum of -7 and -4 is indeed -11, and their product equates to 28.

Step 3: The Act of Factoring

With our numbers in hand, we can proceed to factor the equation, which results in the following expression:

(x – 7)(x – 4) = 0

Step 4: Solving for ‘x’

To ascertain the values of ‘x,’ we set each factor equal to zero:

  1. x – 7 = 0
  2. x – 4 = 0

Upon solving these equations, we attain the following solutions:

  1. x = 7
  2. x = 4

Thus, we have successfully determined that the roots of the quadratic equation x2-11x+28=0 are x = 7 and x = 4.
