Question

How many solutions does 9x^2+ 6x + 1 = 0 have?

(a) one real and one nonreal complex solution
(b) two distinct real solutions
(c) one real solution with multiplicity 2
(d) two nonreal complex solutions
(e) one nonreal complex solution with multiplicity 2

Answer 1

(c). one real solution

Explanation:

9x² + 6x + 1 = 0

D = 6² - 4(9)(1) = 0 ⇒ one real solution with multiplicity 2

Answer 2

Answer: I am pretty sure it is c
