Answer:
3x(4−7y)
Step-by-step explanation:
Hi there!
12x−21xy
12 and 21 are both divisible by 3. Factor 3 out of the expression:
= 3(4x−7xy)
The terms 4x and 7xy both contain x. Let's factor this out:
= 3x(4−7y)
Because the terms inside of the brackets have no more common factors remaining, this expression is now fully factored.
I hope this helps!
