Answer 1

Step-by-step explanation:

x

2

−x+1,−5x

2

+2x−2 and 3x

2

−3x+1

The sum of (x

2

−x+1),(−5x

2

+2x−2) and (3x

2

−3x+1) is calculated as shown below

(x

2

−x+1)+(−5x

2

+2x−2)+(3x

2

−3x+1)

=x

2

−5x

2

+3x

2

+2x−x−3x+1+1−2

=−x

2

−2x

Hence, the sum of (x

2

−x+1),(−5x

2

+2x−2) and (3x

2

−3x+1) is −x

2

−2x

Answer 2

Answer:

Step-by-step explanation:

((x2)-x)-(1/2)((x-3)+3x2))

((x2) -  x) -  (1/2 • (3x2 + x - 3))

-9    +    1    =    -8  

   -3    +    3    =    0  

   -1    +    9    =    8    

Conclusion : Trinomial can not be factored
