Write the absolute value in the form |x-b|=c (where b is a number and c can be wither a number or and expression) that has the following solution set.

Two solutions: x=-2, x=-32

Answer:

  |x +17| = 15

Step-by-step explanation:

The values that go into your absolute value equation template can be found by solving the template equation, then matching results to the desired solution values.

  |x -b| = c

resolves to ...

  x -b = c . . . . for x -b > 0

  x = b+c

and

  -(x -b) = c . . . for x -b < 0

  x = b -c . . . . . solve for x

__

The value of c must be positive, so the value b+c will be the most positive solution:

  -2 = b +c . . . . . the most positive solution

  -32 = b -c . . . . the most negative solution

Adding these equations gives ...

  2b = -34   ⇒   b = -17

  c = -2 -b . . . . from the first equation

  c = -2 -(-17) = 15

Putting the found values b=-17, c=15 into the absolute value equation template gives ...

  |x +17| = 15
