Answer:

10x - 20

Explanation:

distribute the 3 and the 7 into the parentheses, getting you to (3x - 6) + (7x - 14), from there you should be able to just combine the like terms getting you to 10x - 20.

Answer:

  • 10(x - 2)

--------------------

We see x - 2 is the common factor in the given expression.

Simplify as:

  • (x - 2)(3 + 7) =
  • (x - 2)(10) =
  • 10(x - 2)
