Answer:
you want to simplify the fractions to decimals so its easier to put in order
Step-by-step explanation:
Hello there! We are given the following equation and want to simplify it:
![(x+y+2)(y+1)](https://tex.z-dn.net/?f=%28x%2By%2B2%29%28y%2B1%29)
First, let's use the Distributive Property:
For this step, we are going to let:
After applying this version of the Distributive Property, we are given the equation:
![(y)(x+y+2)+(1)(x+y+2)](https://tex.z-dn.net/?f=%28y%29%28x%2By%2B2%29%2B%281%29%28x%2By%2B2%29)
We're going to use the distributive party again, but a slightly different version that's almost the same as first:
Using this on both terms of the equation changes the equation to:
![(xy+y^2+2y)+(x+y+2)](https://tex.z-dn.net/?f=%28xy%2By%5E2%2B2y%29%2B%28x%2By%2B2%29)
Now, we just remove the parenthesis and combine like terms
![y^2+3y+xy+x+2](https://tex.z-dn.net/?f=y%5E2%2B3y%2Bxy%2Bx%2B2)
This should be your answer. Let me know if you need any clarifications, thanks!
