Answer:
GCF: x^5y
Step-by-step explanation:
4x^5 y^12 = x^5y (4y^11)
x^15 y = x^5y (x^10)
8x^10 y^8 = x^5y (x^5y^7)
So
GCF of 4x^5 y^12 - x^15 y + 8x^10 y^8 = x^5 y
Let's see it...
-x+0+(-x)=0 ???
There is a + before the parenthesis, the sign is the same.
-x+0-x = 0
Since the x have equal sign, we add them to get -2x
We have 2x - 0 = 0
Move the zero to the right, so 2x = 0
Divide both for 2...
x = 0
Substitute 0 to x, so -0+0+(-0) = 0
0 = 0 the statement is true
We want to list the steps involved in multiplying fractions;
Taking an example;

First steps are;
- Multiply the numerators together
- Multiply the Denominators together

Next is to;
Check to see if the product can be simplified;

So, we get the product to be;
Here are a few equations I thought of that could fit that solution:
1.) 5x + 3 = 13
2.) 7x - 3 = 11
3.) 4(2x + 5) = 36
