1. (4x³+12x²)-(x-3) = 4x²(x+3)-1(x+3) = (4x²-1)(x+3)
2. (2x³-x²)+(18x-9) = x²(2x-1)+9(2x-1) = (x²+9)(2x-1)
3. (4x³+2x²)-(12x-6) = 2x²(2x+1)-6(2x+1) = (2x²-6)(2x+1)
4. (x⁴-3x³)+(x-3) = x³(x-3)+1(x-3) = (x³+1)(x-3)

3.x do 2 (4x+2)-3(4x-2)
2.x(2x do 2-x)+3(6x-3)
1. 2x do 2(2x+6)-1(x-3) nie jestem pewna tego
