To simplify this expression, we first factorize the denominator of the fraction.
The denominator can be factorized as follows:
x^2 - 49 = (x + 7)(x - 7)
x^2 - 5x + 6 = (x - 2)(x - 3)
x^2 + 4x - 21 = (x + 7)(x - 3)
Therefore, the denominator becomes (x + 7)(x - 7) • (x - 2)(x - 3)/(x + 7)(x - 3)
When we multiply all terms, we'll get:
(x + 7)(x - 7)(x - 2)(x - 3)/(x + 7)(x - 3)
= (x - 7)(x - 2)
What is the answer
3. x^2- 49/x - 2 • x^2 - 5x + 6/x^2+ 4x-21
