Question

Subtract the sum of (a + b + c) and (2a - b + 2c) from 3a - b + 3c. Name the type of expression formed.​

Answer 1

a+b+c + 2a-b+2c = 3a+3c

so 3a-b+3c---3a+3b=-b

$\mathcal\pink{Question}$

Subtract the sum of (a + b + c) and (2a - b + 2c) from 3a - b + 3c. Name the type of expression formed.

$\mathcal\pink{Solution:}$

According to question,

(3a - b + 3c) - [(a + b + c) + (2a - b + 2c)]

= (3a - b + 3c) - [(a + b + c + 2a - b + 2c)]

= (3a - b + 3c) - (3a + 3c)

= (3a - b + 3c - 3a - 3c)

= -b

The given expression contains only -b, So it is a manamial.
