Answer:
1st sum of 2x²-4x+11 and 7x²-4x+1
=>9x²-8x+12---equation 1
2nd step:sum of 8x²-7 and 6x²+4x-6
=>14x²+4x-13---equation 2
Subtract equation 1 from 2
14x²+4x-13 - (9x²-8x+12)
= 5x²+12x-25
6)
1st step:sum of 4x²y-3xy²+4 and -3x²y-7xy²-7
= x²y-10xy²-3---equation 1
Subtract equation 1 from x²+4
x²+4 - (x²y-10xy²-3) =x²-x²y+10xy²+7
