Answer:

The answer to your question is Momentum =
((x + 2)^(2))/(x - 3)

Explanation:

Data

mass =
(x^(2)+ 4x + 4 )/(x^(2)- 9)

velocity =
(x^(2)+ 5x + 6)/(x + 2)

Formula

Momentum = mass x velocity

Substitution

Momentum =
(x^(2)+ 4x + 4)/(x^(2)- 9) (x^(2) + 5x + 6)/(x + 2)

Factor The first numerator is a perfect square trinomial and the second one is a trinomial of the form x² + bx + c.

Momentum =
((x + 2)^(2))/((x - 3)(x + 3)) ((x + 2)(x + 3))/(x + 2)

Simplify and result

Momentum =
((x + 2)^(2))/(x - 3) or
(x^(2) + 4x + 4)/(x - 3)
