When we talk about these situations, we often refer to limits, such as "the speed limit is 65 miles per hour" or "I have a limit of 250 text messages per month." However, we don't have to travel at exactly 65 miles per hour on the highway, or send and receive precisely 250 test messages per month—the limit only establishes a boundary for what is allowable.

In these cases, solving quadratic equations by factoring is a bit simpler because we know factored form, y= (x-r_1) (x-r_2) y = (x− r1)(x− r2), will also have no coefficients in front of x x. We simply must determine the values of r_1 r1 and r_2 r2. But no need to worry, we include more complex examples in the next section.
