Answer:
Please specify the question, but I assume this is boolean algebra so the answer would be:
A + B
Step-by-step explanation:
AB + A + B
Now we are solving the above expression using Boolean theorems:
Factoring
(1+B)A+(1+A)B
Identity Law A+1=1
1A+(1+A)B
Identity Law:A.1=1
A+(1+A)B
Identity Law A+1=1
A+1B
Identity Law:A.1=1
A+B
