Помогите мне пожалуйста

Answer 1

8х^2+16xy+8y^2=8(x^2+2xy+y^2)=8(x+y)^2
-2a^2+24ab-72b^2=2(-a^2+12ab-36b^2)=2(a^2-12ab+36b^2)=2(a-b)^2

Answer 2

-12b^3-12b^2-3b=3b(-4b^2-4b-1)=3b(2b+1)^2

Answer 3

48m^3n-72m^2n+27mn=3mn(16m^2-24m+3)=3mn(4m-3)^2

Answer 4

(x^4-16)=(x^2-4)(x^2-4)

Answer 5

исправь (x^4-16)=(x^2-4)(x^2+4)
