Final answer:

To expand the expression (3x - 5)(2x + 1), multiply the terms in each pair of parentheses together and simplify the resulting expression.

Step-by-step explanation:

To expand the expression (3x - 5)(2x + 1):

  1. Multiply the terms in the first pair of parentheses together: 3x * 2x = 6x^2
  2. Multiply the terms in the inside pair of parentheses together: 3x * 1 = 3x
  3. Multiply the terms in the outside pair of parentheses together: -5 * 2x = -10x
  4. Multiply the terms in the last pair of parentheses together: -5 * 1 = -5
  5. Combine all the terms: 6x^2 + 3x - 10x - 5
  6. Simplify: 6x^2 - 7x - 5

The expanded form of the expression (3x - 5)(2x + 1) is 6x^2 - 7x - 5.
