Given : The expression (x^2-1)(x+2)(x^2-x-72)/(x-9)(x+1)

To find: The lowest term of (x^2-1)(x+2)(x^2-x-72)/(x-9)(x+1).

Solution:

  • Now we have given the expression:  (x^2-1)(x+2)(x^2-x-72)/(x-9)(x+1)
  • Simplifying it, we get:

                  (x^2-1)(x+2)(x^2-x-72)/(x-9)(x+1)

                  (x - 1)(x + 1)(x + 2)(x^2 + 8x - 9x - 72) / (x - 9)(x + 1)

  • Simplifying further, we get:

                  (x - 1)(x + 1)(x + 2)(x(x + 8) - 9(x + 8)) / (x - 9)(x + 1)

                  (x - 1)(x + 1)(x + 2)(x - 9)(x + 8) / (x - 9)(x + 1)

  • Now cancelling the common terms from numerator and denominator, we get:

                  (x - 1)(x + 2)(x + 8)

Answer:

 So the lowest term of (x^2-1)(x+2)(x^2-x-72)/(x-9)(x+1) is (x - 1)(x + 2)(x + 8)
