Answer 1

Nr B:
x = -7 +/- √(-64)
x = -7 +/- 8*√-1
x = -7 +/- 8i

Answer 2

In this case it is to find the roots of the polynomial.
 We have then:
 x ^ 2 + 14x + 17 = -96
 Rewriting:
 x ^ 2 + 14x + 113 = 0
 Applying resolver we have
 x = (- b +/- root (b ^ 2 - 4ac)) / (2a)
 Substituting values:
 x = (- (14) +/- root ((14) ^ 2 - 4 (1) (113))) / (2 (1))
 x = (- (14) +/- root ((196 - 452)) / (2 (1))
 x = (- 14 +/- root (-256))) / (2)
 x = (- 14 +/- i * 16)) / (2)
 x = (- 7 +/- i * 8)
 Answer:
 x = (- 7 +/- i * 8)
