FIND THE SUM OF THE GIVEN POLYNOMIAL:
1. 3x-4x+7xy+9xy-10x+2y
- 7xy+9xy+3x-4x-10x+2y
- 16xy-11x+2y
2. 2a-4a²+9a²+12ab-7a
- -4a²+9a²+12ab+2a-7a
- 5a²+12ab-5a
3. 4x²y+8xy²-23x²y+8x²y²
- 8x²y²+4x²y-23x²y+8xy²
- 8x²y²-19x²y+8xy²
4. 23nm-13n³m+5nm+9n³m
- -13n³m+9n³m+23nm+5nm
- -4n³m+27nm
5. 6r²-8r²+10r²+6r+16r
To find the sum, just combine like terms.
example:
- 2x+2x = 4x
- 2x²+x² = 3x²
- 4xy-6xy = -2xy
