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
