Answer:

$ab-2bc+ca$

Step-by-step explanation:

Complete question is given below

Add:-

ab-bc+ac,bc-ca+ab,ca-ab-2bc

We have to find the result after addition

Now, adding all expression

We get

$ab-bc+ac+bc-ca+ab+ca-ab-2bc$

Combine like terms then, we get

$(ab+ab-ab)+(bc-bc-2bc)+(ac-ca+ca)$

$ab-2bc+ca$

Hence, $ab-bc+ac+bc-ca+ab+ca-ab-2bc=ab-2bc+ca$
