Answer:
x = -1
Explanation:
x² + 6x = -5
x² + 6x -( -5) = 0
- Use the quadratic formula
 - Evaluate the exponent
 - Multiply the number
 - Subtract the number
 - Evaluate the square root
 - Multiply the number
 
x = (-x + 4)/2
To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.
x = (-6 + 4)/2
x = (-6 - 4)/2
- Rearrange and isolate the variable to find each solution
 
x = -1
