Answer:

  • A) (x + 3)² = 0

Step-by-step explanation:

  • A) (x + 3)² = 0 ⇒ x + 3 = 0 ⇒ x = - 3 ⇒ one real solution
  • B) (x + 3)² = -9 ⇒ x + 3 = √-9 ⇒ no real solutions
  • C) (x + 3)² = 9 ⇒ x + 3 = ± 3 ⇒ x = - 3 ± 3 ⇒ two real solutions
  • D) (x + 3)² = 27 ⇒ x + 3 = ± 3√3 ⇒ x = - 3 ± 3√3 ⇒ two real solutions
