Answer

The final solutions to the equation are 5 and 1.

Steps

Step 1 :Rewrite the absolute value equation as two separate equations, one for when the value inside the absolute value is positive and one for when it is negative.

Step 2 :For the positive case, the equation becomes x2+8=11, which simplifies to x+6=11.

Step 3 :Solving for x in the positive case gives the solution x=5.

Step 4 :For the negative case, the equation becomes (x2)+8=11, which simplifies to 10x=11.

Step 5 :Solving for x in the negative case gives the solution x=1.

Step 6 :The final solutions to the equation are 5 and 1.
