Final answer:
The distance between the x-intercepts can be calculated using the formula |x₁ - x₂|.
Step-by-step explanation:
To calculate the distance between the x-intercepts, we can use the formula |x₁ - x₂|. This formula represents the absolute value of the difference between the x-coordinates of the two intercepts. By taking the absolute value, we ensure that the distance is always positive.
For example, if the x-intercepts are at x₁ = 3 and x₂ = -2, the distance would be |3 - (-2) | = |5| = 5.
Therefore, the correct option is A) |x₁ - x₂|.
