X² - 3x - 10

x² = x * x
10 can be factored:
1 x 10 ⇒⇒⇒ difference between factors = 9
2 x 5   ⇒⇒⇒ difference between factors = 3  ⇒ (The correct pair)

(x-5)(x+2) = x(x+2) - 5(x+2)
                 = x² + 2x - 5x - 10
                 = x² - 3x - 10

∴ x - 5 = 0  ⇒⇒⇒ x = 5
   x + 2 = 0  ⇒⇒⇒ x = -2

I have attached <span>algebra tiles for the given equation.</span>

Answer:

{x| -2 ≤ x < 5}

Step-by-step explanation:

The domain is the x value in a graph, function e.t.c. From the farthest point to the left of the x-axis, we see -2. And from the farthest point to the right of the x-axis, we see 5. Therefore, the domain is {x| -2 ≤ x < 5}, Option C
