1) (3x²+5x-28) + 4(x-4) - 2(3x²+3x-20)
2) (11x²+7x-55) - (5x²-3x+1) + (3x²+5x-28) - (2x²+4x+28)
3) (3x²+5x-28) + 4(x-4) + 2(3x²+3x-20)
4) (11x²+7x-55) - (5x²-3x+1) - (3x²+5x-28) + (2x²+4x+28)

Answer 1

The expressions that are equivalent to the given polynomial are: (3x²+5x-28) + 4(x-4) - 2(3x²+3x-20), (11x²+7x-55) - (5x²-3x+1) + (3x²+5x-28) - (2x²+4x+28), (3x²+5x-28) + 4(x-4) + 2(3x²+3x-20), and (11x²+7x-55) - (5x²-3x+1) - (3x²+5x-28) + (2x²+4x+28).

Step-by-step explanation:

1. (3x²+5x-28) + 4(x-4) - 2(3x²+3x-20)
2. (11x²+7x-55) - (5x²-3x+1) + (3x²+5x-28) - (2x²+4x+28)
3. (3x²+5x-28) + 4(x-4) + 2(3x²+3x-20)
4. (11x²+7x-55) - (5x²-3x+1) - (3x²+5x-28) + (2x²+4x+28)
