Answer 2

Answer:

Question: Write the coefficients of x² in each of the following:

[Total: 4 Average: 4.3]

(i) 2 + x2 + x

(ii) 2 – x2 + x3

(iii) (π/2)x2 + x

(iv) √2x – 1

Solution 2:

(i) 2 + x2 + x , the coefficient of x2 is 1

(ii) 2 – x2 + x3, the coefficient of x2 here is -1.

(iii) (π/2)x2 + x, here the coefficient of x2 is π/2.

(iv) √2x – 1, the coefficient of x2 is 0.
