и) x(x2+x) – (x2+x+1) = к) 2y2(6y – 1)+3y(y – 4y2) =
л) a(2a2 – 3n) – n(2n2+a) = м) b(b3 – b2+b) – (b3 – b2+b) =

Answer 1

$(a + 2) \times 6 \\ - 2(x - 3) \\ 4x - 40 \\ - 17 \\ {x}^{2} - 6x \\ 13xy - 9y \\ 6dc - 3 {d}^{2} - 3 {c}^{2} \\ 5 {b}^{2} - 3 {a}^{2} \\ x ^{3} - x - 1 \\ y ^{2} \\ {b}^{4} - {b}^{3}$
