Practice problem
Which of the following is not a step in simplifying (x−3)(3x2−x+1)(x - 3)(3x^2 - x + 1)(x−3)(3x2−x+1)?
3x3−x2+x−9x2+3x−33x^3 - x^2 + x - 9x^2 + 3x - 33x3−x2+x−9x2+3x−3
(x)(3x2)+(x)(−x)+(x)(1)+(−3)(3x2)+(−3)(−x)+(−3)(1)(x)(3x^2) + (x)(-x) + (x)(1) + (-3)(3x^2) + (-3)(-x) + (-3)(1)(x)(3x2)+(x)(−x)+(x)(1)+(−3)(3x2)+(−3)(−x)+(−3)(1)
3x3−10x2+4x−33x^3 - 10x^2 + 4x - 33x3−10x2+4x−3
(x)(−3)+(x)(3x2)+(x)(−x)+(x)(1)(x)(-3) + (x)(3x^2) + (x)(-x) + (x)(1)(x)(−3)+(x)(3x2)+(x)(−x)+(x)(1)
Type a concept, like “slope” or “photosynthesis”.
