Question

2. Write the coefficients of x- in each of the following:
T
(1) 2 + x2 + x
(ii) 2 - x2 + x3
2
x + x
(iv) 2x-1
2​

Answer 1

Answer:

(i) 2 + x2 + x (ii) 2 – x2 + x3 (iii) (pi/2 )x2+ x (iv) √2x – 1

Solution: (i) 2 + x2 + x

Coefficient if x2 = 1

(ii) 2 – x2 + x3

Coefficient of x2 = -1

(iii) (pi/2 )x2+ x

Coefficient of x2 = pi/2

(iv) √2x – 1

Answer 2

Answer:

(1) p(x)= x^2+x+2

coefficient of x= 1

(2) p(x)= -x^2+3x+2

= coefficient of x= 3
