Answer 1

Step-by-step explanation:

Given Equation is x² + x - (a + 2)(a + 1) = 0

⇒ x² - ax - x + ax + 2x - (a + 2)(a + 1) = 0

⇒ x² - (a + 1)x + (a + 2)x - (a + 2)(a + 1) = 0

⇒ x{x - (a + 1)} + (a + 2){x - (a + 1)}= 0

⇒ {x - (a + 1)}{x + (a + 2)} = 0

⇒ x = a + 1 (or) x = -(a + 2)

Hope it helps!

Answer 2

Answer:

Step-by-step explanation:

→ x² + x - (a + 2)(a + 1) = 0

→  x² - ax - x + ax + 2x - (a + 2)(a + 1) = 0

→  x² - (a + 1)x + (a + 2)x - (a + 2)(a + 1) = 0

→  x{x - (a + 1)} + (a + 2){x - (a + 1)}= 0

→  {x - (a + 1)}{x + (a + 2)} = 0

→  x = a + 1 (or) x = -(a + 2)
