Answer:
less than/equal to -2
Or, greater than/equal to 2.5
Step-by-step explanation:
2x² - x - 10 ≥ 0
2x² - 5x + 4x - 10 ≥ 0
x(2x - 5) + 2(2x - 5) ≥ 0
(x + 2)(2x - 5) ≥ 0
Roots: -2, 5/2
x《 -2 or x》5/2
When competing the square, you want to have

at the end, and using the fact that the x term and coefficient are really

, we see that the third option is the most efficient way to start
