Answer:

$\large\boxed{x^3+x^2+2x^2y+2xy+xy^2+y^2}$

Step-by-step explanation:

Use FOIL: (a + b)(c + d) = ac + ad + bc + bd

$(x^2+2xy+y^2)(x+1)\\\\=(x^2)(x)+(x^2)(1)+(2xy)(x)+(2xy)(1)+(y^2)(x)+(y^2)(1)\\\\=x^3+x^2+2x^2y+2xy+xy^2+y^2$

1 · 2/11 = x (Used the opposite reciprocal and changed to multiplication. This is the same as dividing with the original fraction.)

2/11 = x
