Answer:
2x - 4xy or 2x(1 - 2y)
Explanation:
Simplify 4xy-2x+4x-8xy
We can start by rearranging the expression;
4xy-8xy -2x + 4x
Then we add or subtract numbers with the same variable
-4xy + 2x
We can further factorize the above since 2x is common between the two numbers, so we will factor out 2x
2x(-2y + 1)
This can be re-write as;
2x(1 - 2y)
