Answer:
Step-by-step explanation:
i assume x+y=6(1/2)=\frac{13}{2}
Answer:
12) 26x^2+22x+25
13) -15x^2-21x-11
14) x^2+32x+18
15) 9x^6+10x^5-15x^4+14
Step-by-step explanation:
The simplified polynomial is; xy(x²y - xy² +1) and; the value when x=-3 and y=2 is; -186
From the polynomial given;
The polynomial can be factorised to yield a simpler form as follows;
This is so because, xy is a common factor.
The value is therefore;
- (-3×2)((-3)²2 - (-3×2²) +1)
= -186
