Bricks for solving x2-11x+28=0 It is important to note that second-degree algebras, which are also referred to as quadratics, take a standard form of ax^2 + bx + c =0. As seen earlier, the word ‘quadratic’ originating from the Latin word ‘quadratus’ simply means ‘square’. In other words, an “equation of degree 2” is also known as quadratic equation.
Quadratic equation is applied in many different circumstances as used in the above equation. You will be surprised to know that even the path of a rocket that you see being launched from the space center can also be explain by the help of quadratic equation . A quadratic equation has many applications in such areas as star watching, engineering, physics, and in a number of other punishments.
quadratic equation has two solutions of which both could be real or even complex integers. This two solutions (Values of x) are represent as (α, β) they are also called the roots of the quadratic equation. In the content that follows we shall find out more about what is in store as constituent of the quadratic equation’s root.
What is Quadratic Equation?
Quadratic equation is an algebraic equation of second degree in x only namely ax^2 + bx + c = 0 where a, b, c are constants and their values are fixed. The general format of the quadratic equation is ax² + bx + c = 0, and within this format and x is term as the variable while b and c are known as the constants of the variables and c as a constant factor. Another requirement that every quadratic equation (a ≠ 0) must possess is that, the coefficient of x2 must carry a non zero term. It is important to notice that the x2 term comes first and the x term comes second and the constant term follows when putting a quadratic equation in its standard forma = 1
b = -11
c = 28
Factoring the Quadratic Equation
Quadratic problems can be solved in part by factoring. The goal for x2-11x+28=0 quadratic formula
factorization into two binomials, which then multiply to yield the original equation. We are looking for two numbers that multiply to the constant term 28 and add up to the middle term’s coefficient of -11. We can now rewrite the equation using these values:
There are now two components left in the equation:
- x – 7 = 0
- x – 4 = 0
Solving Equation: x-7=0
To isolate x, add seven to either side:
x=7
To isolate x, multiply both sides by 4:
x=4
Roots of the Quadratic Equation
You will enter the value in the equation when you have obtained the value from the equation.
x = 7
x = 4
These values are the quadratic equation x2-11x+28=0 quadratic formula’s roots or solutions. Stated otherwise, the following will occur if we substitute these numbers 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
Both values of x serve as the quadratic equation’s roots and solve the problem.
