Answer 2

To simplify the given expression, let's first combine like terms in the numerator and the denominator:

Numerator: U^2 - 7 + (-24) = U^2 - 31

Denominator: y^2 - 6y + (-9y) = y^2 - 15y 6y - y^2 + (-3y) = 3y - y^2 y^2 - 6y = y^2 - 6y

Now, let's rewrite the expression:

(U^2 - 31) / (y^2 - 15y) - (3y - y^2) / (y^2 - 6y)

Next, factor out the common terms:

(U^2 - 31) / (y(y - 15)) - (y(y - 3)) / (y(y - 6))

Now, find the least common denominator (LCD), which is (y - 15)(y - 6):

(U^2 - 31)(y - 6) / (y(y - 15)(y - 6)) - (y(y - 3)(y - 15)) / (y(y - 6)(y - 15))

Now, combine the fractions:

[(U^2 - 31)(y - 6) - y(y - 3)(y - 15)] / (y(y - 6)(y - 15))

And that's the simplified expression.
