Answer: x = −6±√−52/2
Explanation:
Step 1: Subtract -22 from both sides.
x2+6x−(−22)=−22−(−22)
x2+6x+22=0
For this equation: a=1, b=6, c=22
1x2+6x+22=0
Step 2: Use quadratic formula with a=1, b=6, c=22.
x = −b±√b2−4ac/2a
x = −(6)±√(6)2−4(1)(22)/2(1)
x = −6±√−52/2
If we wanted to simplify this more, it wouldn't be possible because there are no real solutions.
