The document provides 5 examples of writing quadratic equations in the standard form of ax^2 + bx + c = 0. Each example expresses a given equation in terms of x and then identifies the coefficients a, b, and c. For example 1, the equation x^2 = 5 - 2x is written as x^2 + 2x - 5 = 0, with a = 1, b = 2, c = -5. The examples demonstrate how to rearrange various equations involving x terms and constants into the standard quadratic form.
