Add the given polynomial :
a. X-6x'y + 3xy +y': 4x° +5x'y + 3xy-y": --4xy + 2y
b. 4-x-x';x' + x-5x +5; 5x -7x +6;6x-7
x+4x + y + 9x":3x-10x +3-7x®
7xy + 5yz-3zx; 5y + 9zx - 4yz; 5x-2xy
a + 2b + 3c-4d, 4d + 3c-a. 3c-7d-2b
6. Subtract the first polynomial from the second :
a. -9xy: -6UX
b. 4d-7c-3a; a + 2b + 3c-7d
3a - 4 + 6a; 4a-7a-3
d. -5x + 7y2 + 5x’y - 8xy, 3x -8y-2xy + 7xy
C.
