Given:

A = 2p + 3pq - 4q

B = -4pq + 2q -3p  or in rearranged form: -3p - 4pq + 2q

C = -q + 7pq + 2q

To find: A + B - C

A + B = 2p + 3pq - 4q +  -3p - 4pq + 2q = -1p - 1pq - 2q

A + B - C = -1p - 1pq - 2q - (-q + 7pq + 2q) = -1p - 1pq - 2q + q - 7pq - 2q

= -1p - 8pq -1q


Hope it helps :)



Anonymous: your answer is wrong
Equestriadash: How?
Anonymous: it is supposed to be -1p -8pq -3q
Equestriadash: How will -3q come?
Anonymous: But anyhow i have given you brainest
Anonymous: It will your like terms should be -pp,-1pq,-7pq,-2q,-2q+q
Anonymous: so -2q-2q+q is supposed to be -3q
Equestriadash: Then the question must be wrong because -4q+2q-2q = -4q
sumansinghhdr: It really helpful for me
Equestriadash: Oh. Thanks!

a +b-c
putting values of a ,b , c
= 2p+3pq-4q+(-4pq)+2q-3p-(-q)+7pq-2q
as 2q was positive it came to left side and became negative
=2p-3p+3pq-4pq+7pq-4q+2q-q-2q
then I arranged according to the variables
=-p+6pq-5q
in the above step i just add and subtract
and I got the answer


hope it helps you
plzz mark it as brainliest answer
