You can factor this
x^2 + 10x + 16 = 0

(x + 8)(x + 2) = 0

so x + 8 =0 or x + 2 = 0

x = -8, -2

Answer:

0.8745.

Step-by-step explanation:

P(success) = 0.09 and P(failure) = 1 - 0.09 = 0.91.

P( at least 6 failures) = P( less than 2 successes)

= 7C0 (0.09)^0 (0.91)^7 + 7C1 (0.09)(0.91)^6

= 0.5168 + 0.3577

= 0.8745.
