Your answer is C. 2x²/x² + 2x - 15

To find the product, you multiply, and to multiply fractions, you just multiply​ across, so:
2x × x = 2x²
(x - 3) × (x + 5)
To multiply those two expressions, you simply need to expand and simplify
x × x = x²
-3 × x = -3x
5 × x = 5x
-3 × 5 = 15
So altogether you get x² + 2x - 15 as your denominator, which is how you get your answer.

I hope this helps!
