(v) a3 – 3ab + 7a + 9 is a polynomial

(vi) 2x3 + 7xy + 3x + 2 is a multinomial

(vii) 1 + 2x + 3x2 + x4 + x5 is a binomial

(viii) p2 + q2 + r2 is a trinomial


2. Which of the following expressions are polynomials?

(i) 10 – 13x

(ii) z + z2 + z5 - 7

(iii) 1 + 1/a + 1/a2 + 1/a3 +1/a4

(iv) (m2 + m – 2)/(m – 3)

(v) 1/2 – 5/(4 + u)

(vi) 1 + 5m

(vii) 1 + 5u + 4u2

(viii) 1/√x + 5
