Answer» (i) Given a2 a2 is a monomial expression because it contains only one term (ii) Given a2 − b2 a2 − b2 is a binomial expression because it contains two terms (iii) Given x3 + y3 + z3 x3 + y3 + z3 is a trinomial because it contains three terms (iv) Given x3 + y3 + z3 + 3xyz x3 + y3 + z3 + 3xyz is a quadrinomial expression because it contains four terms (v) Given 7 + 5 7 + 5 is a monomial expression because it contains only one term (vi) Given a b c + 1 a b c + 1 is a binomial expression because it contains two terms (vii) Given 3x – 2 + 5 3x – 2 + 5 is a binomial expression because it contains two terms (viii) Given 2x – 3y + 4 2x – 3y + 4 is a trinomial because it contains three terms (ix) Given x y + y z + z x x y + y z + z x is a trinomial because it contains three terms (x) Given ax3 + bx2 + cx + d ax3 + bx2 + cx + d is a quadrinomial expression because it contains four terms |
