Question

Solve it Fast. First correct answer is Brainlist Answer.​

Answer 1

(i) 7a-3b+5c+2a-3b-4c+c-4a+b

=> 7a-4a+2a-3b-3b+b+5c-4c+c

=> 5a-5b+2c

(ii) -7x²-3xy+10y²+8xy+2x²-11y²+8y²-3x²+6xy

=> -7x²+2x²-3x²+10y²+8y²-11y²-3xy+8xy+6xy

=> -8x²+7y²+11xy

Answer 2

Answer:

hope it helps u

mark me as the brainliest if u think its right

Step-by-step explanation:

Such questions can be solved quite easily by simply adding the numerical values of  those terms whose variables are similar.

1)( 7a - 3b + 5c ) + ( 2a - 3b - 4c ) + ( c - 4a + b )

=7a-3b+5c+2a-3b-4c+c-4a+b

= 7a-4a+2a-3b-3b+b+5c-4c+c

On simplifying further,

5a - 5b + 2c

(ii) -7x²-3xy+10y²+8xy+2x²-11y²+8y²-3x²+6xy

= -7x²+2x²-3x²+10y²+8y²-11y²-3xy+8xy+6xy

on simplifying it further

= -8x²+7y²+11xy
