Answer:

x equals -1 and it also equals -13. They are both considered the roots.

Step-by-step

  1. (x+6)^2= 49    to get rid of the exponent square root each side of the equation.
  2. (x+6)= √49     Find square root of 49.
  3. (x+6)= ±7        It could be positive 7 or -7 because both of them squared equal 49. Now solve for each possible equation, (x+6)= 7 and  (x+6)=-7.
  4. (x+6)=7  subtract 6 from each side.
  5. x= 1
  6. (x+6)=-7  Subtract 6 from each side.
  7. x=-13
  8. So the answers are -13 and 1.
