Zapisz w postaci sumy algebraicznej: A. (x+1)(x+2)(x+3) B. (x-2)x+5)(2x-1) C. (x-4)(x+1)(x+1) D. (2x-3)(2x-3)(x+2)
A.(x+1)(x+2)(x+3)=(2x++x+2)(x+3)=3++2x+3+9x+6=+6+11x+6
B.(x-2)(x+5)(2x-1)=(+5x-2x+10)(2x-1)=2-+6-3x+20x-10=2+5+17x-10
C.(x-4)(x+1)(x+1)=(+x-4x-4)(x+1)=-3-4x+-3x-4=-2-7x-4
D.(2x-3)(2x-3)(x+2)=(4-6x-6x+9)(x+2)=4+8-12-24x+9x+18=4-4-15x+18
