Question

How do I simplify efficiently?
3(x-2)+7(x-2)

Answer 1

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 2

• 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)
