Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Factoring Quadratic Equations

Factoring is a method used to solve quadratic equations by expressing them as a product of their linear factors. In the equation 2x^2 - 7x = 0, we can factor out the common term, which simplifies the equation and allows us to find the values of x that satisfy it.

Zero Product Property

The Zero Product Property states that if the product of two factors equals zero, at least one of the factors must be zero. This principle is crucial when solving factored equations, as it allows us to set each factor equal to zero to find the solutions for the variable.

Quadratic Formula

The Quadratic Formula, x = (-b ± √(b² - 4ac)) / (2a), provides a method for solving any quadratic equation of the form ax² + bx + c = 0. While not necessary for this specific problem, it is a valuable tool for finding solutions when factoring is not straightforward or possible.
