Multiple Choice

Expand the product (x+5)(x+3).

Explanation:
Multiplying two binomials uses the distributive property: multiply each term in the first binomial by each term in the second, then combine like terms. For (x+5)(x+3), multiply x by x to get x^2, x by 3 to get 3x, 5 by x to get 5x, and 5 by 3 to get 15. Combine the x-terms: 3x + 5x = 8x. The constant term is 15. Put together: x^2 + 8x + 15.
