 Hello and welcome to the session. In this session we discussed the phonic question which says identify the monomials, binomials and trinomials in the following. Minus 3abc, 2 plus 5xyz, 2x plus 3y plus 5z. Let's see the solution. Minus 3abc contains only one term which is minus 3abc of course and therefore we say that it is a monomial. Then we have 2 plus 5xyz. This expression contains two terms which are 2 and 5xyz and therefore we say that it is a binomial. Then we have another expression which is 2x plus 3y plus 5z. This contains three terms which are 2x 3y 5z and therefore we say that it is a trinomial. So the first expression which is minus 3abc is a monomial, the second expression 2 plus 5xyz is a binomial and the third expression 2x plus 3y plus 5z is a trinomial. So this completes the session. Hope you have understood the solution of this question.
