Answer
3x3 - 4x2 + 5x - 6 - (- 3x3 + 4x2 - 5x + 6)
= 3x3 - 4x2 + 5x - 6 + 3x3 - 4x2 + 5x - 6
Arrange the polynomial with like terms together and combine them.
= (3x3 + 3x3) + (- 4x2 - 4x2) + (5x + 5x) + (- 6 - 6)
= 6x3 - 8x2 + 10x - 12
Hence, 3x3 - 4x2 + 5x - 6 - (- 3x3 + 4x2 - 5x + 6) = 6x3 - 8x2 + 10x - 12.
