Answer:
When we subtract the sum of 2x²y-3xy+5 and 5xy+10x²y from the sum of 7xy+8 and 3x²y-8xy-2, we get -9x²y-3xy+1.
Step-by-step explanation:
Sum of 2x²y-3xy+5 and 5xy+10x²y is
= 2x²y+10x²y-3xy+5xy+5
=12x²y+2xy+5------->eqn1
Sum of 7xy+8 and 3x²y-8xy-2 is
=3x²y+7xy-8xy+8-2
=3x²y-xy+6---------->eqn2
Given that we should subtract eqn1 from eqn2
i.e.,
(3x²y-xy+6)-(12x²y+2xy+5)=3x²y-xy+6-12x²y-2xy-5
=3x²y-12x²y-xy-2xy+6-5
= -9x²y-3xy+1
