Set 1: Quadratic Equations (Intermediate)

Choice A is correct. Choice A is the correct answer. 1. Roots: $x = 2$ and $x = 5$. 2. Direction: The leading term is $x^2$ (positive), so it opens upward. 3. Inequality: We want $> 0$ (above the axis). 4. Region: For an upward parabola, positive values are on the "outside" tails. 5. Solution: $x < 2$ or $x > 5$. Choice B is incorrect because that is where it is negative (between roots). Choice C is incorrect because it misses the left tail. Choice D is incorrect because it misses the right tail.
