Answer 2

To simplify the expression (5/x - 7 - 2/x) / (3x + 28)/(x^2 - 49), we can follow these steps:

Step 1: Simplify the numerator.

The numerator of the expression is (5/x - 7 - 2/x). To simplify this, we can find a common denominator and combine the fractions:

(5/x - 2/x) - 7 = (5 - 2) / x - 7 = 3/x - 7

Step 2: Simplify the denominator.

The denominator of the expression is (3x + 28)/(x^2 - 49). We can factor the denominator:

x^2 - 49 = (x - 7)(x + 7)

Step 3: Simplify the expression.

Now that we have the simplified numerator and denominator, we can simplify the entire expression:

(3/x - 7) / (3x + 28)/(x^2 - 49)

= (3/x - 7) * (x^2 - 49) / (3x + 28)

= (3(x - 7)(x + 7)) / (3x + 28)

So, the simplified form of the expression is (3(x - 7)(x + 7)) / (3x + 28).
