Question

Помогите решить номер 5.130 (2,4,6)

Answer 1

$displaystyle tt 2): 6x^2-12xy+6y^2=6(x^2-2xy+y^2)=6(x-y)^2=underline{bold{6(x-y)(x-y)}}$

$displaystyle tt 4): 5m^2+10m+5=5(m^2+2m+1)=5(m+1)^2=underline{bold{5(m+1)(m+1)}}$

$displaystyle tt 6): 3a-6ab+3ab^2=3a(1-2b+b^2)=3a(1-b)^2=underline{bold{3a(1-b)(1-b)}}$
