Q. 24.5( 4 Votes )

Write the coefficient of x2 and x in each of the following

i. 2 + 3x – 4x2 + x3

ii. √3 x + 1

iii. x3 + √2 x2 + 4x – 1

iv.

Answer :

i 2 + 3x – 4x2 + x3


Co-efficient of x2 = -4


Co-efficient of x = 3


ii √3x + 1


Co-efficient of x2 = 0


Co-efficient of x = √3


iii x3 + √2x2 + 4x – 1


Co-efficient of x2 = √2


Co-efficient of x = 4


iv



= x2 + 3x + 6 = 0


Co-efficient of x2 = 1


Co-efficient of x = 3
