Practice problem
Which one of the following expressions is not equal to 3x3+2x+4x2−8x3+6−4+2x23x^3 + 2x + 4x^2 - 8x^3 + 6 - 4 + 2x^23x3+2x+4x2−8x3+6−4+2x2?
(3x3−8x3)+(4x2+2x2)+2x+(6−4)(3x^3 - 8x^3) + (4x^2 + 2x^2) + 2x + (6 - 4)(3x3−8x3)+(4x2+2x2)+2x+(6−4)
(3−8)x3+(4+2)x2+2x+(6−4)(3 - 8)x^3 + (4 + 2)x^2 + 2x + (6 - 4)(3−8)x3+(4+2)x2+2x+(6−4)
5x3+2x2+2x−25x^3 + 2x^2 + 2x - 25x3+2x2+2x−2
−5x3+6x2+2x+2-5x^3 + 6x^2 + 2x + 2−5x3+6x2+2x+2
