Question

1) 4x²+2x-5+x²-6+(-3x²+x)=

2) 2x-10+2-6x+x²-6=

3) -3x²+x-(x²-6)=

4) 2-6x-(-3x+1)=

5) (-3x+1)·(2x-10)=

6) (x²-6)·(2-6x)=

Answer 1

1) 4x²+2x-5+x²-6+(-3x²+x)=4x²+2x-5+x²-6-3x²+x=2x²+3x-11

2) 2x-10+2-6x+x²-6=x²-4x+-14

3) -3x²+x-(x²-6)=-3x²+x-x²+6=-4x²+x+6

4) 2-6x-(-3x+1)=2-6x+3x-1=-3x-1

5) (-3x+1)·(2x-10)=-6x²-30x+2x-10=-6x²-28x-10

6) (x²-6)·(2-6x)=2x²-6x³-12+36x=-6x³+2x²+36x-12
