What is Factoring?

Factoring is a method of solving quadratic equations by expressing them as a product of two binomials. This involves finding two numbers or expressions that multiply together to give the original quadratic expression. Factoring is an essential skill in mathematics, as it allows us to solve quadratic equations and understand the properties of functions.

Why is Factoring Important?

Factoring is an important concept in mathematics because it allows us to solve quadratic equations and understand the properties of functions. Quadratic equations are used to model real-world problems, such as the trajectory of a projectile or the growth of a population. By factoring quadratic equations, we can gain insights into the behavior of these functions and make predictions about their behavior.

Step-by-Step Instructions for Factoring Quadratic Equations

To factor a quadratic equation, we need to follow these steps:

Write the quadratic equation in the form $ax^2 + bx + c = 0$ : The quadratic equation we are working with is $2x^2 - 7x + 6 = 0$ .
Find two numbers whose product is $ac$ and whose sum is $b$ : In this case, $a = 2$ , $b = -7$ , and $c = 6$ . We need to find two numbers whose product is $2 \times 6 = 12$ and whose sum is $-7$ .
Write the quadratic equation as a product of two binomials: Once we have found the two numbers, we can write the quadratic equation as a product of two binomials. For example, if the two numbers are $-3$ and $-2$ , we can write the quadratic equation as $(2x - 3)(x - 2) = 0$ .

Factoring the Quadratic Equation $2x^2 - 7x + 6 = 0$

To factor the quadratic equation $2x^2 - 7x + 6 = 0$ , we need to find two numbers whose product is $2 \times 6 = 12$ and whose sum is $-7$ . After some trial and error, we find that the two numbers are $-3$ and $-2$ . Therefore, we can write the quadratic equation as:

$2x^2 - 7x + 6 = (2x - 3)(x - 2) = 0$

Solving for $x$

To solve for $x$ , we need to set each factor equal to zero and solve for $x$ . In this case, we have:

$2x - 3 = 0$ or $x - 2 = 0$

Solving for $x$ , we get:

$x = \frac{3}{2}$ or $x = 2$
