Wired Faculty App

How many terms are there in each of the following polynomials? Write them for each polynomial.

(i) 3x2 - 5x + 7    (ii) t - 7t2 + 5 - t3
(iii)    x4 - 3x2 + 2    (iv) 5 - 3y + 2y6
(v)    7    (vi) 3 - 2x.

Solution

(i) 3x2 - 5x + 7
Number of terms = 3
Terms: 3x2, - 5x, 7.
(ii)    t - 7t + 5 - t3
Number of terms = 4
Terms: t, - 7t2, 5, - t3.
(iii)    x4 - 3x2 + 2
Number of terms = 3
Terms: x4, - 3x2, 2.
(iv)    5 - 3y + 2y6
Number of terms = 3
Terms: 5, - 3y, 2y6.
(v)    7
Number of term = 1
Term: 7 (only).
(vi)    3 - 2x
Number of terms = 2
Terms: 3, - 2x.
