 Hi and welcome to the session. Let us discuss the following question. Question says, identify the terms and their factors in the following expressions. Show the terms and factors by three diagrams. E part is minus AB plus 2B square minus 3A square. Let us now start with the solution. Now we have given expression minus AB plus 2B square minus 3A square. Now in this expression we are having three terms. They are minus AB, 2B square and minus 3A square. We know parts of an expression which are formed separately first and then added are called terms. First we form terms and then we add these terms to form an expression. In simple words we can say terms are parts of an expression separated by plus sign. Now we will find factors of these terms. Factors of term minus AB are minus 1A and B. We know minus AB is the product of minus 1A and B. So its factors are minus 1A and B. Now similarly 2B square is a product of 2B and B. So its factors are 2B and B. Similarly we can find factors of this term. This term is equal to product of minus 3A and A. So this is the required tree diagram. We can represent the terms and factors of an expression conveniently and elegantly by a tree diagram. Now this completes the session. Hope you understood the solution. Take care and have a nice day.
