prosze o rozwiązanie ;D

(x-y)(x+y)(x-1)=

(x-2)(x-3)(x-4)=

(a-b)(a-b)(a+b)=

(x+6)(x-1)-(x=2)(x-7)=

x(x-8)-(x+2)(x-3)+

Answer 1

odp1.=(x^2+xy-xy-y^2)(x-1)=(x^2-y^2)(x-1)=x^3-x^2-xy^2-y^2=0

odp2=(x^2-3x-2x-6)(x-4)=(x^2-x-6)(x-4)=x^3-6x^2-x^2-4x-6x-24=x-2x-5x^2-24

0dp3=(a^2-ab-ab-b^2)(a+b)=(a^2-b^2)(a+b)=a^3+a^2b-ab^2-b^3

odp4=(x^2-x+6x-6)-(x^2-7x+2x-14)=x+6x-6-x^2-5x-14=7x-6-x^2-5x-14=2x-20-x^2

0dp5=(x^2-8x)-(x^2-3x+2x-6)=x^4-3x^3+2x^3-6x^2-8x^3-24x^2-16x^2-48x=x^4-x^3-14x^3-40x^2=x^4-15x^3-40x^2
