(1) x3 + x + 1 (1) 2 - x + (ii) (2x +5
(iv) 2x + 5
2
(v)
x²+x
x
2.
(vi)
(vii) 2x2 +5
(vi) 4
3​

Answer 1

Answer:

(i)x

2

+x+1

coefficient of x in this is 1.

(ii)2 - x + x(ii)2−x+x

coefficient of x in this is -1.

(iii)2x + 5(iii)2x+5

coefficient of x in this is 2.

(iv)2x + 13(iv)2x+13

coefficient of x in this is also 2.

(v)x + x(v)x+x

coefficient of x is 1,1.

(vi) \frac{ - 2}{3} {x}^{3}(vi)

3

−2

x

3

coefficient of x is 0.

(vii)2 {x}^{2} + 5(vii)2x

2

+5

coefficient of this is also 0
