Answer 1

Answer:

  x = ±5

Step-by-step explanation:

Multiply by (x-1)(x+1) and you get ...

  (x+1) - (x -1) = (x -1)(x +1)/12

  24 = x^2 -1 . . . . simplify and multiply by 12

  0 = x^2 -25 . . . subtract 24

  0 = (x -5)(x +5) . . . factor the difference of squares

Values of x that make the factors 0 are x=5 and x=-5.

The solutions are x=-5 or x=5.

_____

Subtracting the right side gives an equation that has its solutions at the x-intercepts of the left-side expression. These are seen to be -5 and +5 in the attached graph.
