Q2 of 157 Page 8

Identify the terms and their coefficients for the following expressions:

i. 3abc - 5ca


ii. 1 + x + y2


iii. 3x2 y2 - 3xyz + z3


iv.


v.

i. 3abc - 5ca



The terms are 3ab and -5ca


Coefficient of 3ab = 3


Coefficient of -5ca = -5


ii. 1 + x + y2



There are 3 terms 1,x and y2


Coefficient of 1 = 1


Coefficient of x = 1


Coefficient of y2 = 1


iii. 3x2 y2 - 3xyz + z3



There are 3 terms 3x2 y2, - 3xyz, and + z3


Coefficient of 3x2 y2 = 3


Coefficient of- 3xyz = -3


Coefficient of + z3 = 1


iv. -7 + 2pq – qr + rp



v. 0.3xy



Thus, we can conclude
