What is the simplified polynomial and the value
Elanso [62]

The simplified polynomial is; xy(x²y - xy² +1) and; the value when x=-3 and y=2 is; -186

From the polynomial given;

  • x²yxy -xy²xy +xy.

The polynomial can be factorised to yield a simpler form as follows;

  • xy(x²y - xy² +1).

This is so because, xy is a common factor.

The value is therefore;

  • (-3×2)((-3)²2 - (-3×2²) +1)

  • -6(18+12+1)

= -186
