Practice problem
Which of the following is not a step in foiling (x3−2x)(3x2+1)(x^3 - 2x)(3x^2 + 1)(x3−2x)(3x2+1)?
(x3)(−2x)+(3x2)(−2x)+(x3)(1)+(3x2)(1)(x^3)(-2x) + (3x^2)(-2x) + (x^3)(1) + (3x^2)(1)(x3)(−2x)+(3x2)(−2x)+(x3)(1)+(3x2)(1)
(x3)(3x2)+(x3)(1)+(−2x)(3x2)+(−2x)(1)(x^3)(3x^2) + (x^3)(1) + (-2x)(3x^2) + (-2x)(1)(x3)(3x2)+(x3)(1)+(−2x)(3x2)+(−2x)(1)
3x5+x3−6x3−2x3x^5 + x^3 - 6x^3 - 2x3x5+x3−6x3−2x
