i) x³ + x + 1 

ii) 2 – x³ + x²

iii)√2x³ + 5

iv) 2x³ + 5

v) π/2 x³ + x

vi) - 2/3 x³

vii) 2x² + 5

viii) 4

Answer 1

Write the coefficient of x³ in each of the following.

i) x³ + x + 1 : co-efficient of x³ is 1.

ii) 2 – x³ + x²  : co-efficient of x³ is – 1.

iii)√2x³ + 5 : co-efficient of x³ is √2

iv) 2x³ + 5 : co-efficient of x³ is 2

v) π/2 x³ + x : co-efficient of x³ is π/2

vi) - 2/3 x³ : co-efficient of x³ is -2/3

vii) 2x² + 5 : co-efficient of x³ is '0'.

viii) 4 : co-efficient of x³ is '0'.
