Equations help to make clear the relationships between a large variety of variables, which makes them crucial to the study of mathematics. Both mathematicians and amateurs have been captivated by the intriguing equation x2+(y-3−x2)2=1. The objective of this essay is to explain this strange equation and discuss its applications, graphical representation, solution, and significance to contemporary mathematics.

Known About Quadratic Equation

We must first understand what a quadratic equation is in order to set off on this quest. A second degree polynomial equation with the squared variable as its characteristic is called a quadratic equation. We get a quadratic equation, also known as a second degree polynomial problem, when we solve for x. It is usually expressed as follows: ax2 + bx + c = 0. The equation x2-11x+28=0 gives us:

a = 1

b = -11

c = 28

Factoring the Quadratic Equation

Factoring is one way to solve quadratic problems. The objective is to factor the equation x2-11x+28=0 into two binomials that multiply to get the original equation. We are searching for two values that sum up to the middle term’s coefficient -11 and multiply to the constant term 28. With these values, we can now rewrite the equation:

  1. Solving for x

The equation may now be divided into two parts:

  • x – 7 = 0
  • x – 4 = 0
  • Solving Equation: x-7=0

Add 7 to both sides to isolate x:


  • Solving Equation: x–4=0

Add 4 to both sides to isolate x:


Roots of the Quadratic Equation

Once you get the value from the equation then will put the value in the equation.

x = 7

x = 4

The quadratic equation x2-11x+28=0 has roots or solutions represented by these numbers. Stated otherwise, the following will be true if we replace these values back into the original equation:

For x = 7:

7² – 11(7) + 28 = 49 – 77 + 28 = 0

For x = 4:

4² – 11(4) + 28 = 16 – 44 + 28 = 0

The roots of the quadratic equation are both values of x, which fulfill the equation.
