-8x^2y^4z^3 + 12x^4 yz^3 =
-4x^2 y z^3 ( 2y^3 - 3x^2)
Do you see how I did that, T4H???
OK
Take out the lowest common factor beteen - 8 and 12.....to make matters simple....I'll use 4 in this example
Take out the lowest common factoe between x^2 and x^4 = x^2
Take our the lowest common factor between y^4 and y = y
Take out the lowest common factor between z^3 and z^3 = z^3
On the outside of the parentheses we will just write these in order = 4x^2yz^3
To find out what goes in the parentheses we just fivide each term in the original problem by 4x^2y z^3
So -8x^2y^4z^3 And 12x^4yz^3
___________ = -2y^3 ________ = 3x^2
4x^2yz^3 4x^2 y z^3
Putting this all together we get
4x^2yz^3 ( -2y^3 + 3x^2)
