Answer 1

Answer:

We have to subtract 2a−5b+2c−9 from 3a−4b−c+6

So, simply numeric coefficients of same varaibles will be subtracted.

∴(3a−4b−c+6)−(2a−5b+2c−9)

=(3−2)a+(−4−(−5))b+(−1−2)c+(6−(9))

=a+b−3c+15

Answer 2

=>(3a-4b-c+6)-(2a+5b+2c-9)

=>3a-4b-c+6-2a-5b-2c+9

=>a-9b-3c+15

Thus , when we subtract 2a+5b+2c-9 from 3a-4b-c+6

we get a-9b-3c+15
