Practice problem
Which of the following is not a step in simplifying (2x+y)(x−2y)(2x + y)(x - 2y)(2x+y)(x−2y)?
(2x)(y)+(2x)(x)+(2x)(−2y)+(y)(x)+(y)(−2y)(2x)(y) + (2x)(x) + (2x)(-2y) + (y)(x) + (y)(-2y)(2x)(y)+(2x)(x)+(2x)(−2y)+(y)(x)+(y)(−2y)
(2x)(x)+(2x)(−2y)+(y)(x)+(y)(−2y)(2x)(x) + (2x)(-2y) + (y)(x) + (y)(-2y)(2x)(x)+(2x)(−2y)+(y)(x)+(y)(−2y)
2x2−4xy+xy−2y32x^2 - 4xy + xy - 2y^32x2−4xy+xy−2y3
2x2−3xy+2y32x^2 - 3xy + 2y^32x2−3xy+2y3
Type a concept, like “slope” or “photosynthesis”.
