do 5, 6 ​

Answer 1

Answer:

1.5x² +5x-25

2.x²y+10xy²+x²+7

Step-by-step explanation:

1.)sum of 2x²-4x+11 and 7x²-4x+1

→ 9x²-8x+12

sum of 8x²-7x-7 and 6x²+4x-6

→14x²-3x-13

Subtraction of 9x²-8x+12 from 14x²-3x-13 is 5x² +5x-25

2.) sum of 4x²y-3xy²+4 and -3x²-7xy²-7 is

x²y-10xy²-3

subtraction of x²y-10xy²-3 from x²+4 is x²y+10xy²+x²+7
