Answer:

  • 15x -45
  • 3(5x -15)

Step-by-step explanation:

The expression can be fully factored as ...

  3·5·(x-3)

Equivalent expressions can be formed by eliminating parentheses to give ...

  15x -45

or by combining different pairs of factors:

  • 3(5x -15)
  • 5(3x -9)

Of course any of the terms can be broken apart and/or combined in different ways:

  = 15(x -2) -15

  = (7x -7) + 2(4x -19)
