Answered by maham237 @
Start with
x2 +14x + 17 = -96
set equal to 0
x2 +14x + 113 = 0
use quadratic formula
= (-14 +/- sqrt(196 - 4(1)113)) // 2
=( -14 +/- 16i ) // 2)
= -7 +/- 8i
Step - start by setting the equation equal to 0
Use quadratic formula
Note the discriminant is negative therefore answer is a complex number.
Simplify
