Question

Zapisz w jak najprostszej postaci.

1.(3-x)-(x-3)=

2.-5(a-4)-7(3-2a)=

3.(5-x)

4.12-4(k+1) / 2 =

5.

6. 2(n-3) - 4n+ 1

---------

2

7. x+3/ 2 - 4x+ 2 / 4 =

8._

Answer 1

1.(3-x)-(x-3)= -2x+6
2.-5(a-4)-7(3-2a)= 9a-1
3. (5-x) = 3x²+3x-1,5

4.2-4(k+1) / 2 = -2k+10

5.  =x√2+3√2-2

6.2(n-3) - (4n+ 1)/2 = 10

7= x+3/ 2 - 4x+ 2 / 4 = -3x+2

8.= 5x²y²+2xy-y²-x²+1
