To find the domain of the expression x² + 2/x² - 7x + 10, we need to identify values of x that make the denominator zero.x² - 7x + 10 = (x - 2)(x - 5) = 0x = 2 or x = 5The denominator x² cannot be zero, so:x ≠ 0The domain is all real numbers except x = 0, 2, and 5.Domain: (-∞, 0) ∪ (0, 2) ∪ (2, 5) ∪ (5, ∞)In interval notation:[tex] \text{Domain}= ℝ \ {0, 2, 5}[/tex]
