Help! I think I am right, but not sure.
Factor out greatest common factor then simplify the factors
15wx-20wy-25wz=
5w(3x)+5w(-4y)+5w(-5z)=
5w(3w-4y-5z)=
5w
Where did the x go?
Other than what I assume is a typo, everything looks good.
Sorry, I should have put
5w(3x-4y-5z)=5w
To factor out the greatest common factor, you first need to identify the terms that can be divided by a common factor. In this case, the greatest common factor of the terms 15wx, -20wy, and -25wz is 5w.
So, you can rewrite the expression as:
15wx - 20wy - 25wz = 5w(3x) - 5w(4y) - 5w(5z)
Notice that each term now has a common factor of 5w. To simplify the expression further, you can factor out 5w from each term:
= 5w(3x - 4y - 5z)
Now, the expression is fully factored and simplified. The final answer is 5w(3x - 4y - 5z).
