Question

Subtract the polynomials

1 (7x+2) from (-6x+8)
2 3xy+5yz - 7xz+1 from - 4xy+2yz-2xz+3xyz+1
3 2xSquare ySquare - 3xy +4 from 4xSquare ySquare +10xy​

Answer 1

Answer:

1) 1(7x+2) -(-6x+8)

7x+2+6x-8

13x-6

2)_4xy+2yz_2xz+3xyz+1

(-) 3xy+5yz - 7xz++1

= _7xy+7yz_9xz+3xyz+2

3) 4x^2y^2+10xy

(-)2x^2y^2_3xy +4

= 2x^2+7xy+4
