Introduction

Quadratic equations are a fundamental concept in mathematics, and they play a crucial role in various fields such as physics, engineering, and economics. A quadratic equation is a polynomial equation of degree two, which means the highest power of the variable is two. In this article, we will focus on solving quadratic equations using the method of factorization.

What is Factorization?

Factorization is a mathematical technique used to express an algebraic expression as a product of simpler expressions. In the context of quadratic equations, factorization involves expressing the quadratic expression as a product of two binomial expressions. The general form of a quadratic equation is:

ax^2 + bx + c = 0

where a, b, and c are constants, and x is the variable.

The Factorization Method

The factorization method involves finding two binomial expressions whose product equals the quadratic expression. The general form of a binomial expression is:

ax + b

To factorize a quadratic expression, we need to find two binomial expressions whose product equals the quadratic expression. The factorization method involves the following steps:

Identify the coefficients: Identify the coefficients of the quadratic expression, which are the numbers in front of the variable x.
Find the factors: Find two numbers whose product equals the constant term (c) and whose sum equals the coefficient of the linear term (b).
Write the binomial expressions: Write the two binomial expressions using the factors found in step 2.
Multiply the binomial expressions: Multiply the two binomial expressions to get the quadratic expression.

Solving the Quadratic Equation by Factorization

Now, let's apply the factorization method to solve the quadratic equation:

x^2 - 6x + 5 = 0

Step 1: Identify the coefficients

The coefficients of the quadratic expression are a = 1, b = -6, and c = 5.

Step 2: Find the factors

We need to find two numbers whose product equals 5 and whose sum equals -6. The factors of 5 are 1 and 5, but their sum is 6, not -6. We need to find two numbers whose product equals 5 and whose sum equals -6. After some trial and error, we find that the factors are -1 and -5.

Step 3: Write the binomial expressions

Using the factors found in step 2, we can write the two binomial expressions as:

(x - 1)(x - 5)

Step 4: Multiply the binomial expressions

Multiplying the two binomial expressions, we get:

x^2 - 6x + 5

This is the same as the original quadratic expression.

Conclusion

In this article, we have discussed the method of factorization for solving quadratic equations. We have applied the factorization method to solve the quadratic equation x^2 - 6x + 5 = 0. The factorization method involves finding two binomial expressions whose product equals the quadratic expression. We have identified the coefficients, found the factors, written the binomial expressions, and multiplied the binomial expressions to get the quadratic expression.

Real-World Applications

The factorization method has numerous real-world applications in various fields such as physics, engineering, and economics. For example, in physics, the factorization method is used to solve problems involving motion, energy, and momentum. In engineering, the factorization method is used to design and analyze complex systems such as bridges, buildings, and electronic circuits. In economics, the factorization method is used to model and analyze economic systems such as supply and demand, inflation, and unemployment.
