Answer 1

$\huge\green{A}\orange{N}\red{S}\pink{W}{E}\blue{R}$

(i) 2a+b-c-(a-b+c)

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

=a+2b-2c

(ii)  x²-2xy+y²-(x²+2xy+y²)

=x²-2xy+y²-x²-2xy-y²

= -2xy-2xy

= -4xy

(iii) x-3-x²+x³-(x²-3x-3)

=x-3-x²+x³-x²+3x+3

=x-2x²+x³

=x³-2x²+x

(iv) 5x²-2y+3y²-(3x²-y²)

=5x²-2y+3y-3x²+y²

=2x²+y+y²

=2x²+y²+y

Answer 2

Answer:

(i) 2a+b-c-(a-b+c)

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

= a+2b-2c.

(ii)  x²-2xy+y²-(x²+2xy+y²)

=x²-2xy+y²-x²-2xy-y²

= -2xy-2xy

= -4xy.

(iii) x-3-x²+x³-(x²-3x-3)

=x-3-x²+x³-x²+3x+3

=x-2x²+x³

= x³-2x²+x.

(iv) 5x²-2y+3y²-(3x²-y²)

=5x²-2y+3y-3x²+y²

=2x²+y+y²

= 2x²+y²+y.

Hope it helps.

Thanks..
