Practice problem
Which of the following is equal to (x4−1)−(2x3+4x−2)(x^4 - 1) - (2x^3 + 4x - 2)(x4−1)−(2x3+4x−2)?
x4−2x3+4x−3x^4 - 2x^3 + 4x - 3x4−2x3+4x−3
x4−2x3−4x−3x^ 4 - 2x^3 - 4x - 3x4−2x3−4x−3
x4−2x3−4x+1x^4 - 2x^3 - 4x + 1x4−2x3−4x+1
−x4+2x3+4x−1-x^4 + 2x^3 + 4x - 1−x4+2x3+4x−1
Type a concept, like “slope” or “photosynthesis”.
