Question

(xy+yz+xy+10)+(8xy+2yz+5xz)

Answer 1

$(xy+yz+xy+10)+(8xy+2yz+5xz)=xy+yz+xy+10+8xy+2yz+5xz=\\= 10xy+5xz+3yz+10$

Answer 2

To simplify the expression $(xy + yz + xy + 10) + (8xy + 2yz + 5xz)$, you can first combine like terms by adding or subtracting them together. Like terms are terms with the same variables and exponents.

Let's group the like terms:

$xy + xy$ can be simplified to $2xy$. $yz + yz$ can be simplified to $2yz$.

Now, the expression becomes:

$2xy + 2yz + 10 + 8xy + 2yz + 5xz$

Next, combine the like terms again:

$(2xy + 8xy) + (2yz + 2yz) + 10 + 5xz$

$10xy + 4yz + 10 + 5xz$

So, the simplified expression is:

$10xy + 4yz + 10 + 5xz$
