Answer:

The second and third line are wrong

Step-by-step explanation:

(4x³ +4x²-8x) -(8x²-16x+4)

= 4x³ +4x²-8x - 8x²+ 16x -4  

= 4x³ +4x²- 8x²-8x+ 16x -4

= 4x³ -4x²+ 8x -4

In the second line:

it has to be +16x because - times - is +

it is like -1*(8x²-16x+4)

In the third line:

you can only add or subtract the xs with the same exponentation, so

4x²- 8x² and -8x+ 16x

4x²- 8x²= -4x² not +12x²

x = 1 y = 9

x = 2 y = 16

x = 3 y = 24

etc.
