Simplify (x + 3)(x + 5)

  1. 2x2 + 8x + 15

  2. x2 + 8x + 15

  3. 2x2 + 8x + 15

  4. x2 + 8x + 18

The correct answer is: x2 + 8x + 15

Expanding the given expression using the Distributive Property, we get x2 + 5x + 3x + 15. Simplifying further, we get x2 + 8x + 15. Option A and C are incorrect because they have an additional term of 2x compared to the simplified expression. Option D is incorrect because it has a constant term of 18 instead of 15. Option B is the correct answer as it matches the simplified form of the given expression.
