Question

Arrange horizontally and add the given expression.

(1) 12c, 7c
(2) bc², 11bc²
(3) –xyz, 2xyz
(4) –6a²b², –4a²b²
(5) 10p²q, –qp²
(6) a³, –14a³

Solution

(1) We can arrange the like terms as:
12c + 7c
= (12 + 7)c
= 19c

(2) We can arrange the like terms as:
bc² + 11bc²
= (1 + 11)bc²
= 12bc²

(3) We can arrange the like terms as:
–xyz + 2xyz
= (–1 + 2)xyz
= (1)xyz
= xyz

(4) We can arrange the like terms as:
–6a²b² + (–4a²b²)
= (–6 –4)a²b²
= –10 a²b²

(5) We can arrange the like terms as:
10p²q + (–qp²)
= 10 p²q + (–p²q)
= (10 – 1)p²q
= 9 p²q

(6) We can arrange the like terms as:
a³ + (–14a³)
= (1 – 14)a³
= –13a³
