Let us write the co-efficient of the following polynomials according to the guidelines:
(i) The co-efficient of x3 in 5x3 – 13x2 + 2
(ii) The co-efficient of x in x2 – x + 2
(iii) The co-efficient of x2 in 8x – 19
(iv) The co-efficient of x0 in 
Answer :
(i) We can see that with x, the constant written before that is 5,
⇒ The co-efficient of x3 in 5x3 – 13x2 + 2 is 5.
(ii) We can see that with x, the constant written before that is -1,
⇒ The co-efficient of x in x2 – x + 2 is -1.
(iii) We can see that with x2, the constant written before that is 0, because there is no x2 in polynomial.
⇒ The co-efficient of x2 in 8x – 19 is 0.
(iv) We can see that with x0 (i.e., the constant) is √(11)
⇒ The co-efficient of x0 in √ (11) – 3√(11) x+x2 is √(11).
