Question

Помогите решить, очень надо!!!​

Answer 1

a) 2xy-3ay+2x^2-3ax

y(2x-3a)+x(2x-3a)

(2x-3a)*(y+x)

б) a^2b^2+2a^2b+2ab-ab^2

ab(2b+2a+2-b)

в) (x-y)^2+3(y-x)

(x-y)^2+3*(-(-x-y))

(x-y)^2-(x-y)

(x-y)*(x-y-3)

а)4ab-bc+4a^2-ac

b(4a-c)+a(4a-c)

(4a-c)(b+a)

б)x^2y-xy^2-xy+x^2

x(xy-y^2-y+x)

x(y(x-y)-y+x)

x(x-y)(x+1)

в)(a-2)^2-5(2-a)

(a-2)^2-5(-(a-2))

(a-2)^2+5(a-2)

(a-2)(a-2+5)

(a-2)(a+3)
